    Product Description

    Bz-IEGR-pNA is a colorimetric substrate for Factor Xa.1 Factor Xa preferentially binds to and cleaves the Ile-Glu-Gly-Arg (IEGR) peptide sequence to release p-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of Factor Xa activity.

    WARNING This product is not for human or veterinary use.
