Specificity: Detects an ~35 kD protein, corresponding to the apparent molecular mass of syntaxin 2 on SDSPAGE immunoblots, in samples from human, mouse, rat, bovine, canine, chicken, Drosophila, hamster, insect, monkey, pig, rabbit, sheep and Xenopus origins. The antibody specificity has been confirmed by specific peptide inhibition in immunoblotting studies.
