    Customer reviews and Q&As


    Thank you for your enquiry. I have contacted the originators of these antibodies and here is the sequence information I obtained. ab25899: This immunogen sequence is proprietary, but we can run any alignments with the sequence that you require. ab40887: The immunogen is 19aa long peptide that lies within the first 50 aas on N-termincal of human Caspase-5. ab28383/ab28382:LDTLVGKGRFAEVYKAKLKQN (these are the same antibody, one is prediluted and one is concentrated) ab15181: GSGEQPRGGGPTSSC Before buying any of these antibodies, I recommend that you check to make sure they are tested in Western blot and IHC and also make sure they have been tested in the sepcies of the sample you are using. We can only guarantee the antibodies if you use them as they are described on the data sheets. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
