Background of CXCR4
CXCR4 (Chemokine,CXC Motif, Receptor 4), also known as FUSIN or NPY3R, is a protein that in humans is encoded by the CXCR4 gene. It is the receptor for the CXC chemokine SDF1 that has essential functions on embryo organogenesis, immunological functions and T lymphocyte trafficking. CXCR4 is the only SDF1 receptor identified so far. This suggests that CXCR4 expression is critical for the biological effects of SDF1. CXCR4 is also a seven-transmembrane-spanning, G-protein-coupled receptor for the CXC chemokine PBSF/SDF-1. It functions as a co-receptor for T-cell-line tropic human immunodeficiency virus HIV-1. It was concluded that PBSF/SDF-1 and CXCR4 define a new signalling system for organ vascularization.

Question
Will anti-CXCR4 antibody PA2081 work on goat WB with oviduct epithelium?
Verified Customer
Verified customer
Asked: 2020-01-20
Answer
Our lab technicians have not validated anti-CXCR4 antibody PA2081 on goat. You can run a BLAST between goat and the immunogen sequence of anti-CXCR4 antibody PA2081 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 goat 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 goat oviduct epithelium in WB, you can get your next antibody for free.

Question
My question regarding product PA2081, anti-CXCR4 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?
Verified Customer
Verified customer
Asked: 2018-04-05
Answer
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 PA2081 anti-CXCR4 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.

Question
Will PA2081 anti-CXCR4 antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?
A. Evans
Verified customer
Asked: 2016-07-15
Answer
As indicated on the product datasheet, PA2081 anti-CXCR4 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.
