Catalog #: PRO-640
Description:
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.
Synonyms:
BclXL, Bcl-X(L), Bcl-XL.
Source:
Escherichia Coli.
Purity:
Greater than 95.0% as determined by SDS-PAGE.
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.
Formulation:
The protein contains 10mM Tris-HCL pH-8, 1mM EDTA and 250mM NaCl.
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.
Physical Appearance:
Sterile Filtered White lyophilized (freeze-dried) powder.
