Protein Standards
 

Size Standard
Quantitative Standard
Western Standard
BSA Standards

We developed innovative protein standards and staining reagents. Using these standards, you can determine the molecular weight (size) and quantity (mass) of your protein simultaneously. With our staining reagents, you can rapidly stain your protein gel with high sensitivity eliminating hazardous chemicals. We also offer a few enzymes with competitive price and superior quality.

Size Standard

DigiProTM 3-200 protein standard contains protein bands with molecular weights from 3 kD to 200 kD. It consists of 13 polypeptides. Under some electrophoretic conditions, the two insulin polypeptide bands runs together at about 3 kD. Only 12 protein bands will be shown on gel. It is an unstained protein standard that allows accurate estimation of molecular weight of your sample proteins. It also allows rough estimation of quantity of your protein bands.

Quantitative Standard

QuantProTM 3-200 quantitative protein standard contains protein bands with quantities from tens nanograms to hundreds of nanograms. It consists of 13 polypeptides with molecular weights in the range of 3 kD to 200 kD. Under some electrophoretic conditions, the two insulin polypeptide bands runs together at about 3 kD. Only 12 protein bands will be shown on gel. It is an unstained protein standard that allows accurate estimation of molecular weight of your sample proteins. In addition, it also allows you to simultaneously estimate the quantity of each protein band in your protein samples.

Western Standard

HisProTM is a protein standard for Western analysis of his-tagged proteins. It will react with monoclonal or polyclonal antibodies against his-tagged proteins.

BSA Standards

Bovine serum albumin (BSA) is commonly used as a standard in protein quantitation. When it is prepared in liquid, it will be only stable for about 2 weeks at 4 0C. Our BSA standards of different concentrations are stable for six months at 4 0C.
