Target description

Bcl-2-like protein 1 (UniProt: Q07817; also known as Bcl2-L-1, Apoptosis regulator Bcl-X, BCL-xL) is encoded by the BCL2L1 (also known as BCL2L, BCLX) gene (Gene ID: 598) in human. Bcl-xL is the most abundant Bcl-x protein that inhibits apoptosis by various mechanisms including the inhibition of Bax. It binds to Bax and prevents it from binding to the mitochondrial outer membrane. It can also induce the translocation of mitochondrial bound Bax to the cytoplasm, and can sequester tBid, which is an activator of Bax. Bcl-xL also regulates 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. It has four BH motifs. The BH4 motif is essential for its anti-apoptotic activity. The BH1 and BH2 motifs are required for both heterodimerization with other Bcl-2 family members and for repression of cell death. The loop between motifs BH4 and BH3 is required for the interaction with NLRP1. It is proteolytically cleaved by caspases during apoptosis and the cleaved protein that lacks the BH4 motif, has pro-apoptotic activity. Its caspase cleavage site is localized between amino acids 61-62. Bcl-xl undergoes phosphorylation on serine 62 by CDK1. This phosphorylation is partial in normal mitotic cells, but complete in G2-arrested cells upon DNA-damage, thus promoting subsequent apoptosis. Its phosphorylation at serine 49 occurs during the S and G2 phases and disappears rapidly in early mitosis. Overexpression of Bcl-xL has been linked with increased cell survival and higher expression is shown to  promote the progression of breast and urothelial cancers and play a role in chemotherapy resistance.  This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitution

0.3 mg/mL after reconstitution at 25 µL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 µL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.

Other Notes

Concentration: Please refer to the Certificate of Analysis for the lot-specific concentration.
