Question (47250) | Anti-CCK2-R antibody (ab77077)

Go to datasheet (ab77077)


IHC-P, human
crossreactivity with receptor A? check homology


Thank you for contacting us.

I have checked the sequence homology of the immunogen of each antibody witht he sequence of the CCK receptor A.
For ab43404, the homology is 0%, and forab77077, the homology isonly 12.5%. Thus, no cross reactivity with the receptor A can be expected.

ab77077 is guaranteed for human samples and IHC-P, while ab43404 has not yet been tested in IHC-P and you would be eligible to use our testing discount program (please see below for more details).
