Customer reviews and Q&As


Thank you for contacting us.

I performed a protein alignment with the target immunogens and the rabbit protein sequences for the antibodies. We recommend that alignment should be over 85% to predict that an antibody will detect in a different species.

Here are the results, similarities are in %:

ab47027 Anti-CGRP antibody: 85%

ab14184 Anti-Substance P antibody [SP-DE4-21]: 100%

ab106291 Anti-Substance P antibody: 100%

ab2318: As mentioned in the Scientific Support section, PGE2 is a lipid rather than a protein and is therefore not species specific. There should not be any particular problems using this assay to detect PGE2 from rabbit. Optimization for different sample types will have to be done by the end user. Please keep in mind that since PGE2 is a lipid, extraction buffers containing detergents (for preparing tissue samples) are not recommended. Mechanical disruption in a buffer such as PBS is recommended instead. For serum and plasma, simple dilution should be sufficient.

I can offer a discount off a future purchase if your customer buys one or more of the antibodiesnow, test it in rabbit and submit feedback to us in the form of an Abreview. It doesn’t matter whether the Abreview is positive or negative, we would just really like to receive your feedback.

If they are interested in this offer, please let me know.
