SERVA Unstained Protein Standard IV is designed for precise molecular weight determination in SDS PAGE and verification of Western Blotting transfer efficiency. The protein marker covers a broad molecular weight range from 10 to 200 kDa (12 bands, separation on a SDS Tris-Glycine gel). The 25 kDa and 85 kDa bands have double intensity for easy allocation of protein molecular weights. It is provided in a ready-to-use formula and no heating, further dilution or adding of reducing reagents is necessary before use.
The marker is stable for up to two weeks at 25 °C and for up to 3 months at 4 °C.
Recommended loading volume for a mini gel is 5 µl/lane.
