SDS-MW Analysis Kit


SKU #: 390953

For research use only. Not for use in diagnostic procedures.

The SDS-MW Analysis Kit is designed for the sizing of protein-SDS complexes separated in a replaceable gel matrix. The gel is formulated to provide an effective protein sieving range of approximately 10 kDa to 225 kDa. Within this size range the logarithm of protein molecular mass is linear with its reciprocal electrophoretic mobility allowing the molecular weight of an unknown protein to be estimated from a standard curve of known protein sizes. This chemistry can also be used to quantify of protein concentration and to determine the purity of a protein product.
