产品名称:
Streptavidin (TxRd)
产品描述:
Streptavidin is a 55 kDa (subunit MW 14 kDa) biotin-binding protein isolated from Streptomyces avidini. Streptavidin is superior to avidin, because it does not contain carbohydrate like avidin and has no net charge at neutral pH. Streptavidin~biotin system is routinely used in Immunohistochemistry (IHC). Extinction Coefficient 1% A280=32.0; Protein content: > 95%; Texas Red: A max. 596 nm; E max. 620 nm. Fluorochrome / protein Absorbance ratio: A596 nm/ A280 nm.
实验应用:
FCM, ICC/IF

Streptavidin~biotin system is routinely used in Immunohistochemistry (IHC). Extinction Coefficient 1% A280=32.0; Purity: Streptavidin used is 99% pure by HPLC; Eletrophoretically homogenous, single band, Protein content: > 95%; Activity 14.8 units/ mg, one unit bunds 1.0 microgram of d-biotin; Protease activity: 0.000018 units/mg; Isoelectric point: 7.0 +/- determined by Isoelectric focusing. Texas Red: A max. 596 nm; E max. 620 nm. Fluorochrome / protein Absorbance ratio: A596 nm/ A280 nm.
