Human SPP1 (NP_001035147, 17 a.a. - 314 a.a.) partial recombinant protein with His tag expressed in Escherichia coli.
Host:
Escherichia coli
Theoretical MW (kDa):
36.2
Form:
Liquid
Preparation Method:
Escherichia coli expression system
Purity:
> 90% by SDS-PAGE
Endotoxin Level:
< 1 EU per 1 ug of protein (determined by LAL method).
Activity:
Measured by the ability of the immobilized protein to support the adhesion of HEK293 human embryonic kidney cells. When cells are added to OPN coated plates 10 ug/mL. This effect is more to 40%.
Quality Control Testing:
3 ug by SDS-PAGE under reducing condition and visualized by coomassie blue stain.
Recommend Usage:
SDS-PAGE The optimal working dilution should be determined by the end user.
Storage Buffer:
In 20 mM Tris-HCl buffer, 2 mM EDTA, pH 7.5 (1 mM DTT, 10% glycerol).
Storage Instruction:
Store at 2°C to 8°C for 1 week. For long term storage, aliquot and store at -20°C to -80°C. Aliquot to avoid repeated freezing and thawing.
