摘要:
Marker sets are provided for use on nondenaturing gels. The protein molecular weight markers are provided in liquid form, and are stable in liquid form for at least two months at 4 degrees C. and at least one year at −20 degrees C. Methods of using the markers and kits containing stable native protein markers in liquid form for determining molecular mass of proteins using electrophoresis are also provided. Furthermore, methods for generating revenue by selling the liquid molecular weight markers, are provided.

The present invention provides dual labeled protein standards useful for the simultaneous determination of the molecular weight of a subject protein as well as the relative mass (i.e., amount) of the subject protein present in an electrophoresis lane. The invention is also directed to methods suitable for the preparation of such dual labeled protein standards and to methods of using such dual labeled proteins to simultaneously determine the molecular weight and the relative amount of a subject protein. Further embodiments are directed to the use dual labeled protein standards to make a more accurate determination of the amount of a protein present in an electrophoresis lane. Yet further embodiments are directed to kits containing the presently described dual protein standards. Dual labeled protein standards made and used in accordance with the embodiments set forth herein may be used to simultaneously determine the molecular weight and the relative amount of a subject protein in real time.
摘要:
Gels, such as polyacrylamide gels, are provided that include linear polyacrylamide in the stacking gel. Native gels that include linear polyacrylamide in the stacker can be used to separate biomolecular complexes, such as protein complexes. Gel cassettes in which the gap width between front and back plates does not vary by more than 5% at the upper edge of the cassette are also provided. The gel cassettes can be used for electrophoretic separation of proteins and protein complexes on native gels, such as native gels that include linear polyacrylamide in the stacker. The native gels can have multiple wells for electrophoresing at least one sample and/or at least one molecular weight standard.
