This lyophilized preparation is stable for 12 months from date of receipt at -20 to -70 degrees C, preferably desiccated. Upon reconstitution, the preparation can be stored for 1 month at 2-8 degrees C under sterile conditions, and for 3 months at -20 degrees C to -70 degrees C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Stock solutions should be aliquoted and stored at < -20 degrees C. Further dilutions should be made in appropriate buffered solutions

Purity

> 97 % pure by SDS-PAGE and HPLC

Endotoxin Level

Less than 0.1 EU/ug of Bcl-xL as determined by LAL method.

Predicted Molecular Mass

23.7 kDa.
Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

Background: Bcl-xL

Bcl-X, also named as BCL2L1 or BCL2L, belongs to the Bcl-2 family and it is encoded by the BCL2L1 gene in human. Alternative splicing of Bcl-X results in at least two isoforms, isoform Bcl-X(L) (also named as Bcl-xL) and isoform Bcl-x(S) (also named as Bcl-xS). Bcl-xL is found in tissues containing long-lived postmitotic cells, such as adult brain, while Bcl-xS is expressed at high levels in cells that undergo a high rate of turnover, such as developing lymphocytes. Bcl-X forms homodimer or heterodimer with other Bcl-2 proteins, like BAK, BAX or Bcl-2, to act as anti- or pro- apoptotic regulators. Bcl-xL appears to regulate cell death by blocking the voltage-dependent anion channel (VDAC) by binding to it and preventing the release of the caspase activator, CYC1, from the mitochondrial membrane, and it also acts as a regulator of G2 checkpoint and progression to cytokinesis during mitosis. In contrast, Bcl-xS is a pro-apoptotic protein that promotes apoptosis.
