How to test your testosterone
Free Testosterone ELISA KitAre you interested in this product? Would you like to get a quotation or free testosterone ria kit a question? We look forward to your e-mail! Free testosterone diffuses through cell membranes and binds to specific receptor proteins androgen receptors ; the Testosterone-receptor complexes act as transcriptional modulators on cis-regulatory regions of many genes. Excess of Androgens in women causes free testosterone ria kit and signs of virilization; Testosterone level in serum has to be determined before and after ovarian and adrenal stimulation and supression to identify the source of excessive hormone production. Steroid shop nederland and secondary hypogonadism in men result in clinical hypoandrogenization, correlated with the degree of gonadal failure in Testosterone production.

Information on standard material: The formulation of the standard is 0. Reagents include 1 M SO 2. Azide, thimerosal, 2-mercaptoethanol 2-ME or any other poisonous materials are not used. The provided antibodies and their host vary in different kits. All antibodies are affinity purified. The solution should be cooled to room temperature before use.
Prepare standard within 15 minutes before use. Reconstitute the Standard with 1. This reconstitution produces a stock solution. Then make serial dilutions as needed Making serial dilution in the wells directly is not permitted. The Sample Diluent serves as the zero 0. Centrifuge the stock tube before use, dilute the concentrated Biotinylated Detection Ab to the working concentration using Diluent for Biotinylated Detection Ab 1: Contaminated water or container for reagent preparation will influence the result.
Bring all reagents and samples to room temperature before use. Centrifuge the sample again after thawing before the assay. All the reagents should be mixed thoroughly by gently swirling before pepitting. It's recommended that all samples and standards be assayed in duplicate.
Add Sample and Biotinylated Detection Ab: The blank well is added with sample diluent. Cover with the Plate sealer we provided. Gently tap the plate to ensure thorough mixing. Solutions are added to the bottom of micro ELISA plate well, avoid inside wall touching and foaming as possible. Complete removal of liquid at each step is essential to good performance.
After the last wash, remove any remaining Wash Buffer by aspirating or decanting. Invert the plate and pat it against thick clean absorbent paper. Cover with a new Plate sealer. The reaction time can be shortened or extended according to the actual color change, but not more than 30 minutes.
When apparent gradient appeared in standard wells, you can terminate the reaction. Color turn to yellow immediately. The adding order of stop solution should be as the same as the substrate solution. Determine the optical density OD value of each well at once, using a microplate reader set to nm. You should open the microplate reader ahead, preheat the instrument, and set the testing parameters.
After experiment, put all the unused reagents back into the refrigerator according to the specified storage temperature respectively until their expiry.
Average the duplicate readings for each standard and samples. Create a standard curve by plotting the mean OD value for each standard on the y-axis against the concentration on the x-axis and draw a best fit curve through the points on the graph. It is recommended to use some professional software to do this calculation, such as curve expert 1. In the software interface, a best fitting equation of standard curve will be calculated using OD values and concentrations of standard sample.
The software will calculate the concentration of samples after entering the OD value of samples. If samples have been diluted, the concentration calculated from the standard curve must be multiplied by the dilution factor. If the OD of the sample surpasses the upper limit of the standard curve, you should re-test it after appropriate dilution.
The actual concentration is the calculated concentration multiplied dilution factor. You are viewing an incomplete version of our website. Please click here to reload the website as full version.

Limited by existing techniques, cross reaction may still exist, as it is impossible for us to complete the cross-reactivity detection between Chicken F-TESTO and all the analogues. Kreuzreaktivität Details No significant cross-reactivity or interference between chicken Free Testoterone and analogues was observed.
Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between Human bFGF and all the analogues, therefore, cross reaction may still exist. The just opened ELISA Plate may appear water-like substance, which is normal and will not have any impact on the experiment results. For each step in the procedure, total dispensing time for addition of reagents or samples to the assay plate should not exceed 10 minutes.
Parallel measure ment is recommended. To prevent evaporation and ensure accurate results, proper adhesion of plate sealers during incubation steps is necessary. Do not allow wells to sit uncovered for extended periods between incubation steps. Do not let the strips dry at any time during the assay. Strict compliance with the given incubation time and temperature. The wash procedure is critical.
Insufficient washing will result in poor precision and falsely elevated absorbance readings. Residual liquid in the reaction wells should be pat dry against absorbent paper in the washing process. Note that clear the residual liquid and fingerprint in the bottom before measurement, so as not to affect the micro-titer plate reader.
As the volume of Detection Ab and HRP Conjugate is very small, liquid may adhere to the tube wall or tube cap when being transported.
You better hand-throw it or centrifugal it for 1 minute at rpm. Please pipette the solution for times before pippeting. To minimize imprecision caused by pipetting, ensure that pipettors are calibrated. Please control reaction time strictly following this product description! Substrate Solution is easily contaminated. Please protect it from light. As it is an acid solution, please pay attention to the protection of your eyes, hands, face and clothes when using this solution. If there is no micro-oscillator available, you can knock the ELISA plate frame gently with your finger before reaction.
Please wear lab coats and latex gloves for protection. Especially detecting samples of blood or other body fluid, please perform following the national security columns of biological laboratories. Do not use component from different batches of kit washing buffer and stop solution can be an exception To avoid cross-contamination, change pipette tips between adding of each standard level, between sample adding, and between reagent adding. Also, use separate reservoirs for each reagent.
Otherwise, the results will be inaccurate! Kommentare Information on standard material: Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase HRP is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. Probennahme Samples should be clear and transparent and be centrifuged to remove suspended solids.
Collect the supernatant and carry out the assay immediately. Blood collection tubes should be disposable, non-pyrogenic, and non-endotoxin. Collect plasma using EDTA or heparin as an anticoagulant. For general information, hemolysis blood may affect the result, so you should mince the tissues to small pieces and rinse them in ice-cold PBS 0.
Tissue pieces should be weighed and then homogenized in PBS the volume depends on the weight of the tissue with a glass homogenizer on ice.
To further break the cells, you can sonicate the suspension with an ultrasonic cell disrupter or subject it to freeze-thaw cycles. Avoid repeated freeze-thaw cycles. Please predict the concentration before assaying.
If the sample concentration is not within the range of the standard curve, users must determine the optimal sample dilutions for their particular experiments. Testdurchführung Bring all reagents and samples to room temperature before use. Ergebnisberechnung Average the duplicate readings for each standard and samples. Beschränkungen Nur für Forschungszwecke einsetzbar Handhabung All the reagents in the kit should be stored according to the labels on vials.
Unused wells should be returned to the foil pouch with the desiccant pack and resealed along entire edge of zip-seal.
Exposure of reagents to strong light should be avoided in the process of incubation and storage. All the taps of reagents should be tightened to prevent evaporation and microbial contamination. If not to store reagents according to above suggestions, erroneous results may occur.
