- Escherichia Coli
|Product Name:||Human Bcl XL Recombinant Protein|
|Synonyms:||BclXL, Bcl-X(L), Bcl-XL.|
|Physical Appearance:||Sterile Filtered White lyophilized (freeze-dried) powder.|
|Formulation:||The protein contains 10mM Tris-HCL pH-8, 1mM EDTA and 250mM NaCl.|
|Solubility:||Suspend BclXL in 100?l of 0.5M Acetic acid, over night at 4°C. Dilute 10 fold into selected buffer system.Bcl-XL has tendency to form intramolecular disulfide bond, 5mM DTT is recommended in assay buffer. When running SDS-PAGE gel, 10mM DTT is recommended.|
|Stability:||Lyophilized Bcl-XL although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Bcl-XL should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles.|
|Purity:||Greater than 95.0% as determined by SDS-PAGE.|
Bcl-XL is a transmembrane protein located in the mitochondrial membranes of cells that are long-lived and postmitotic, such as adult brain cells. It plays arole in the signal transduction pathway of the FAS-Ligand. Bcl-XL is an anti-apoptotic protein which is a member of the Bcl-2 family which are able to form heterodimers, and this is an significant event in the regulation of apoptosis. BCL-XL is involved in the survival of cancer cells. Bcl-xL is the leading monitor of apoptosis/active cell suicide. Bcl-xL has cell death repressor activity and therefore acts as a survival protein.
Bcl-XL Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing amino acids 1-210.The Bcl-XL is expressed as GST-Tag fusion protein and purified by proprietary chromatographic techniques.
