Please let me ask one question.
Can this kit detect only human CD63? Or is there some cross-reactivity with CD63 of other species(mouse, rat)?

Thanks for your inquiry.
#CSB-E14107h,Human cluster of differentiation 63,CD63 ELISA Kit
This kit is developed based on matrix of human and it is directed to human samples.Human CD63 is a different protein from rat/mouse CD63.The sequence of human CD63 and matrix are different from that of rat/mouse CD63.
And we did not do analysis of cross-reactivity on human DC63 and rat/mouse CD63.If you are going to test rat/mouse sample,the kit of respective species is advised.
If further questions,pls do ont hesitate to cotnact us.

I want to lyse my sample and I will use RIPA buffer for lysis.
Does RIPA buffer has any effect to ELISA result?

Thanks for your inquiry.
Usually RIPA would contains components SDS、Triton X-100、NP-40,ect.Pls kindly be noted that it must not contain SDS which would destroy the hydrogen bonds of protein macromolecules and causes denaturation of proteins .And Triton X-100、NP-40 should be controlled in the concentration range (usually not over 1% which was not validated ever).
For RIPA buffer,we did not ever use this kind of treatment method.You can only try by yourself and do pre-testing.On our side,we use the freeze-thaw method on PBS and we suggest you do the same.
Regarding EGTA and EDTA,they can both be used as chelat to eliminate the interfere of metal ions.They can affect the results from BCA method,but the affect to elisa method is not clear so far.
For 1 mM Na3,we think it might be typed wrong,which should be NaN3.Rigt?NaN3 can not be contained in the sample.Or it will be easily to get false negative result.
For the other components in your RIPA Buffer,we are not clear about their affects to the results.We suggest you use the suggested method.If you have prepared well your sample,you can go on try and do pre-testing.If the sample is not prepared well yet,pls use the suggested method.
For further questions,pls contact us.

I have a one question. Is there any difference in composition between biotin ab. diluent and HRP-avidin diluent?

Thanks for your inquiry.
biotin ab. diluent and HRP-avidin diluent are 2 different components
Biotin-antibody Diluent is for dilutions of Biotin-antibody
HRP-avidin Diluent is for dilutions of HRP-avidin.Pls let me know if you have any further questions. Thank you.

If I use biotin-antibody diluent for HRP-avidin, then Is there any important problem?!

May I know why you would use biotin-antibody diluent for HRP-avidin?Usually we do not suggest that.

Target Background

Function
(From Uniprot)

Functions as cell surface receptor for TIMP1 and plays a role in the activation of cellular signaling cascades. Plays a role in the activation of ITGB1 and integrin signaling, leading to the activation of AKT, FAK/PTK2 and MAP kinases. Promotes cell survival, reorganization of the actin cytoskeleton, cell adhesion, spreading and migration, via its role in the activation of AKT and FAK/PTK2. Plays a role in VEGFA signaling via its role in regulating the internalization of KDR/VEGFR2. Plays a role in intracellular vesicular transport processes, and is required for normal trafficking of the PMEL luminal domain that is essential for the development and maturation of melanocytes. Plays a role in the adhesion of leukocytes onto endothelial cells via its role in the regulation of SELP trafficking. May play a role in mast cell degranulation in response to Ms4a2/FceRI stimulation, but not in mast cell degranulation in response to other stimuli.
