Background of HOXA4

HOXA4 (HOMEOBOX A4), also known as HOX1D or HOMOLOG OF, is a protein that in humans is encoded by the HOXA4 gene, which is also part of the A cluster on chromosome 7. HOXA4 encodes a DNA-binding transcription factor which may regulate gene expression, morphogenesis, and differentiation. Its cytogenetic location is 7q15.2. In vertebrates, the genes encoding the class of transcription factors called homeobox genes are found in clusters named A, B, C, and D on four separate chromosomes. Expression of these proteins is spatially and temporally regulated during embryonic development.

Antibody Validation

Question

We are currently using anti-HOXA4 antibody PA1603 for rat tissue, and we are satisfied with the ICC results. The species of reactivity given in the datasheet says human, mouse, rat. Is it likely that the antibody can work on horse tissues as well?

Asked: 2017-12-29

Answer

The anti-HOXA4 antibody (PA1603) has not been tested for cross reactivity specifically with horse tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in horse you can get your next antibody for free. Please contact me if I can help you with anything.
