Opti-Protein XL Marker

Description

Opti-Protein XL Marker/Ladder consists of 12 proteins that resolve into sharp, tight bands in the range of 10-245 kDa. This unique 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 two reference bands one green and one red band at 25kDa and 75 kDa respectively when separated on SDS-PAGE Tris-glycine buffer . Specifications Number of Bands 12 Protein Range 10 - 245 kDa Suggested Load Mix gently by pipetting up and down a few times, then directly load 5 mul into the well of the gel.
