Human Dihydrotestosterone (DHT) ELISA Kit
Dear customers, thank you for choosing our products. This product is suitable for in vitro qualitative detection of Human serum, plasma or cell culture supernatant ａnd organizations in the natural ａnd recombinant DHT concentration. Detection of other special sample please contact our technical support. The kit is for research use only. Please read the instructions carefully before using ａnd check the kit components. If you have any questions, please contact SANCHEZ INC You will get our full range of services.
This kit employs Double Antibody Sandwich Technique. The principle of Double Antibody Sandwich is based on characteristics of the tested antigen with more than two valances which can identify coated antibody and detection antibody at same time. The specific process is as follows:
1. Connect the specific antibodies ａnd solid phase carriers to form immobilized antibodies. Wash out uncombined antibodies ａnd impurities. Seal the rest binding sites with irrelevant proteins.
2. Join under test with immobilized antibodies for contact reaction. After a while, combine antigens in ａnd antibodies on carriers into the antigens complex. Wash out uncombined antibodies ａnd impurities.
3. Add biotin labeling antibodies to combine with the antigens on immune complexes. Wash out the uncombined biotin labeling antibodies thoroughly. The enzyme amount on the carrier is now positively related to the amount of the tested substance in specimens.
4. Add horseradish peroxidase to label the avidins ａnd incorporate them with the biotin labeling antibodies. Wash out the incorporated enzyme markers thoroughly. The enzyme amount on the carrier is now positively related to the amount of the tested substance in specimens.
Note: an antibody molecule can be marked on several biotin molecules ａnd a biotin molecule can be connected with a HRP-Avidin to form numbers of horseradish peroxidases combining with antibodies which shows higher sensitivity ａnd amplification effect comparing with traditional direct HRP-Antibodies.
【Detection principle of Human Dihydrotestosterone (DHT) ELISA kit】
This experiment use double-sandwich elisa technique and the ELISA Kit provided is typical. The pre-coated antibody is Human DHT monoclonal antibody ａnd the detecting antibody is polyclonal antibody with biotin labeled. Samples ａnd biotin labeling antibody are added into ELISA plate wells ａnd washed out with PBS or TBS. Then Avidin-peroxidase conjugates are added to ELISA wells in order; Use TMB substrate for coloring after reactant thoroughly washed out by PBS or TBS. TMB turns into blue in peroxidase catalytic ａnd finally turns into yellow under the action of acid. The color depth ａnd the testing factors in samples are positively correlated.
