Protein Markers

G-Biosciences provide two prestained protein molecular weight markers (protein ladder, protein standard). These broad range protein standards are optimized for SDS-PAGE gel electrophoresis in Western Blotting processes. 

PAGEmark™ Blue PLUS Protein Markers

A blue protein standard with 12 prestained proteins covering a wide range of molecular weights: 10-240kDa in Tris-Glycine buffer and 9-235kDa in Bis-Tris (MOPS) buffer or Bis-Tris (MES) buffer.

PAGEmark™ Tricolor PLUS Protein Markers

A ready-to-use three-color protein standard with 13 prestained proteins covering a wide range of molecular weights: 5-245kDa in Tris-Glycine buffer or 3.5-235kDa in Bis-Tris (MOPS) buffer or Bis-Tris (MES) buffer). 

Proteins are covalently coupled with a blue chromophore except for two reference bands. A green chromophore at 25kDa and a red chromophore at 75kDa.
