Prestained Color Protein Marker(10-250kDa)

This prestained color protein marker contains 11 purified proteins spanning from 10 kDa to 250 kDa, with band colors designed for easy identification during electrophoresis. The 72 kDa band appears in orange, the 25 kDa band in green, and the remaining nine bands in blue. This marker is commonly used to monitor protein separation efficiency in SDS-polyacrylamide gel electrophoresis, evaluate Western blot transfer performance onto PVDF, nylon, or nitrocellulose membranes, and estimate protein molecular weight in routine laboratory workflows. In histology laboratories where tissue sections are prepared using Paraffin Microtome, this marker is frequently employed as a quality control reference to verify protein integrity before downstream immunoassay analysis on the same tissue-derived samples. The marker is supplied ready-to-use in loading buffer and requires no heating, dilution, or addition of reducing agents before sample loading. The buffer formulation ensures protein stability and c…
