Quantitative Standard

QuantPro^TM 3-200 quantitative protein standard

QuantPro^TM 3-200 quantitative protein standard contains protein bands with quantities from tens of 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 as above. It is an unstained protein standard that allows accurate estimation of molecular weight of your sample proteins. In addition, it also allows you to estimate the quantity of each protein band in your protein samples. Each protein band in the standard has different quantity with different loading volume as illustrated above. Different loading volumes are useful to estimate different quantity of sample protein. The above gel is stained by ProBlue^TM staining solution. Same size and quantity results will be obtained from regular brilliant blue staining procedures. It is suitable for most polyacrylamide gels. It is supplied in ready-to-load buffer containing SDS and reducing agents. No further mixing, heating, or reducing are required. It is stored at 4 ^oC under liquid condition. No thawing and refreezing are needed. Protein staining method is needed to visualize this standard.

Key Benefits

	Ideal for simultaneously estimating both size and mass of a sample protein or a mixture of proteins
	Chemicals including detergents, lipids, buffers, salts, and reducing agents will not affect the quantity estimations
	ready-to-load eliminating further mixing, heating, reducing, thawing, and refreezing
