Question (76347) | Recombinant Human SNAP25 protein (ab51048)

Go to datasheet (ab51048)


Could you please help me to find the difference between the following four recombinant proteins SNAP25 you are selling?

Catalog numbers are: ab51048, ab87335, ab155885 and ab74529.


I have been in contact with our lab and products team and indeed there is a duplication here which we are currently trying to fix.

I can confirm that ab74529 and ab155885 are identical and ab87335 and ab51048 are also identical.

The difference between ab74529/ab155885 and ab87335/ab51048 is that ab87335/ab51048 is His-tagged whereas ab74529/ab155885 are untagged proteins.

ab87335/ab51048- SNAP25 (Synaptosomal-associated protein) Human, His- tag, Recombinant, E.coli, 25.4 kDa (226 aa), confirmed by MALDI-TOF.
The synaptosomal-associated protein (SNAP-25) is an essential component of the core complex that mediates presynaptic vesicle trafficking. Thus, SNAP-25 is directly involved in the release of neurotransmitters. Recombinant human SNAP25, fused to His tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

ab74529/ab155885 - SNAP25,1-206aa, Human, Recombinant, E.coli, no tag, 23 kDa (206 aa), confirmed by MALDI-TOF.
