7 Customer Q&As for Anti-SR-4 HTR4 Antibody


Does anti-SR-4 antibody A03681-1 work on pig WB with brain?

Verified Customer

Verified customer

Asked: 2020-01-09


Our lab technicians have not tested anti-SR-4 antibody A03681-1 on pig. You can run a BLAST between pig and the immunogen sequence of anti-SR-4 antibody A03681-1 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated pig samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in pig brain in WB, you can get your next antibody for free.

Would A03681-1 anti-SR-4 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

S. Wu

Verified customer

Asked: 2018-12-06


As indicated on the product datasheet, A03681-1 anti-SR-4 antibody as been validated on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.

I am looking for to test anti-SR-4 antibody A03681-1 on mouse epithelium of bronchus for research purposes, then I may be interested in using anti-SR-4 antibody A03681-1 for diagnostic purposes as well. Is the antibody suitable for diagnostic purposes?

W. Johnson

Verified customer

Asked: 2017-09-01


The products we sell, including anti-SR-4 antibody A03681-1, are only intended for research use. They would not be suitable for use in diagnostic work. If you have the means to develop a product into diagnostic use, and are interested in collaborating with us and develop our product into an IVD product, please contact us for more discussions.

Can you help my question with product A03681-1, anti-SR-4 antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?

B. Walker

Verified customer

Asked: 2016-02-09


We do not recommend storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free A03681-1 anti-SR-4 antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.
