FeaturedFeatured Product
ActiveBiologically Active

Description

Human TGFB1, premium grade is expressed from human 293 cells (HEK293). It contains AA Ala 279 - Ser 390.

Images & Validation

Application Notes
This protein carries no "tag". The protein has a calculated MW of 12.8 kDa (monomer). The protein migrates as 14 kDa (monomer) under reducing (R) condition, and 25 kDa (Dimer) when calibrated against Star Ribbon Pre-stained Protein Marker under non-reducing (NR) condition (SDS-PAGE)
