    Streptavidin is a tetrameric protein purified from Streptomyces avidinii. It has wide use in numerous molecular biological protocols dues to its strong affinity for biotin. The original Strep-tag is a nine amino acid peptide with high specificity and affinity towards streptavidin. The addition of this tag to the C-terminus of recombinant proteins allowed the simple purification of protein by use of affinity columns. It was re-engineered (and re-named Strep-tag II) to allow it to also placed at the N-terminus of recombinant proteins.

    Streptavidin is a tetrameric protein purified from Streptomyces avidinii. It has wide use in numerous molecular biological protocols dues to its strong affinity for biotin. The original Strep-tag (AWRHPQFGG) was a nine amino acid peptide with high specificity and affinity towards streptavidin which allows the simple purification of protein by use of affinity columns, but required addition to only the C-terminus of recombinant proteins. To also allow a Strep-tag to be placed at the N-terminus of recombinant proteins, it was re-engineered and re-named Strep-tag II.

Thank you for your reply.

I have processed your request to receive ab119810 as free of charge replacement for ab76949. Currently, ab119810 is out of stock, but we expect to be able to ship it to you by 11th May, I do apologize for this delay....

Thank you for your reply.

Both antibodies should work equally as well for you. I was suggested ab119810, as it is the only other Strep tag antibody we have in stock and the only information that we have on it, is what is already on the webpag...

Thank you for your reply.

I think the best way forward is too either replace or refund the cost of ab76949. An alternative to ab76949 is ab119810:
