Background: Hematopoietic stem cells are known to express a membrane transporter molecule, known as P-glycoprotein (Pgp), that is encoded by the multidrug resistance gene 1 (MDR1) . Expression of Pgp appears to confer a proliferative advantage to stem cells through its anti-apoptotic effects . An additional transporter molecule known as ABCG2 (ATP-binding cassette gene 2) or Bcrp1 (Breast cancer resistance protein 1), first identified in a breast cancer cell line , is expressed on stem cells . ABCG2 belongs to a family of molecules that span the cell membrane six times and can exist as either homo or hetero dimers linked by a short intracellular flexible linker region that plays an important role in the efflux of a wide range of substrates
Bio Acitivity: Not validated for activity
Sequence: Met 1-Gly 300
Purity: > 95% as determined by reducing SDS-PAGE.
Formulation: Lyophilized from sterile PBS, pH 7.4.
Normally 5%-8% trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the printed manual.
Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.
Endotoxin: < 10 EU/mg of the protein as determined by the LAL method.
