Opti-Protein Ultra Marker

With enhanced performance for high molecular weight proteins, Opti-Protein Ultra Marker consists of 10 pre-stained proteins that resolve into sharp, tight bands covering a wide range of molecular weights from 6.5 to 270 kDa. This protein ladder allows you to monitor protein separation during electrophoresis, estimate molecular weight of the protein of interest, and evaluate western blot transfer efficiency. Proteins are covalently coupled with a blue chromophore except for three reference bands (two orange bands at 30 kDa and 270 kDa and one green band at 52 kDa) when separated on gel. Features: Broad range: 6.5 to 270 kDa Ready-to-use: Load directly into gel Easy identification: 3 colored reference bands (orange at 30 kDa and 270 kDa and green at 52 kDa) Clean/Sharp bands: 8 sharp markers visible at 270, 175, 130, 95, 66, 52, 37, and 30 kDa and 2 additional bands at 16 and 6.5 kDa (Tris-Glycine 4-20% Gel) Number of Bands:10 Suggested Load:Mix gently by pipetting up and down a few time, then directly load 5 ul into well of gel.
