Do You Have An ELISA Kit For The Detection Of Serum Amyloid A (SAA) In The Rat?


Written by admin on February 20, 2013. Posted in FAQs

We have been asked on many occasions if our SAA ELISA kit is cross-reactive with rat.

Published reports indicate that rat does indeed possess the gene for SAA, but that the gene contains a deletion. This gene appears to be transcribed and interestingly is under the control of a promoter, an inhibitory regulatory element, and a cytokine response element. Truncated mRNA for SAA can be detected, but the mature protein does not appear in serum or plasma samples.
