EZEE-13, 13 Pre-stained Proteins with 5-colour molecular weights from 5 to 250 kDa 1x500ul vial

EZEE-13 Prestained Protein Ladder contains 13 prestained recombinant proteins spanning a molecular weight range of 5 to 250 kDa, featuring a five-color design for easy band identification. All proteins are covalently labeled with a blue chromophore, with distinct reference bands highlighted in red at 80 kDa, green at 25 kDa, yellow at 15 kDa, and purple at 250 kDa. Optimized for SDS-PAGE, this ladder enables accurate monitoring of protein migration and size estimation, while also allowing assessment of transfer efficiency during Western blotting on PVDF, nylon, or nitrocellulose membranes.
