常见问题解答 (FAQ)

Are there any His-tags on Streptavidin (Cat. No. 434302)?

This Streptavidin is a native protein from Streptomyces avidinii, therefore there are no His-tags on it.

How many biotin binding-sites are there per streptavidin molecule?

Streptavidin is a protein composed of four identical subunits, each containing a high affinity binding site for biotin (K-D = 10 -15 M) . Streptavidin has the same biotin binding properties as avidin, but it has a low isoelectric point (pI=5) and no carbohydrate groups, resulting in low non-specific binding.

Is Streptavidin (Cat. No. S888, 434302, and 434301) RNAse-free?

Although we utilize manufacturing methods that minimize the introduction of any contaminants such as RNases, we do not process this product to specifically remove or inactivate RNases and do not test for RNase activity.
