SAR1B is a small GTPase that functions as a homodimer. GTP-Binding Protein SAR1B (SAR1b) is involved in transport from the endoplasmic reticulum to the Golgi apparatus and also in the selection of the protein cargo and the assembly of the COPII coat complex. The SAR1B protein is activated by the guanine nucleotide exchange factor PREB. SAR1B gene defects are a cause of chylomicron retention disease (CMRD), also known as Anderson disease (ANDD).




Anti-human SAR1B mAb, clone PAT1C7A, is derived from hybridization of mouse F0 myeloma cells with spleen cells from BALB/c mice immunized with a recombinant human MRRF protein 1-198 amino acids  purified from E. coli.

Ig Subclass

Mouse IgG1 heavy chain and Kappa light chain.

Purification Method

SAR1B antibody was purified from mouse ascitic fluids by protein-G affinity chromatography.

Physical Appearance

Sterile Filtered colorless solution.


1mg/ml containing PBS, pH-7.4, 10% Glycerol and 0.02% Sodium Azide.
