Invitrogen™ Human BCL2L2 (BCL-W) ELISA Kit

Description

The Human BCL2L2 (BCL-W) ELISA quantitates Hu BCL2L2 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu BCL2L2. Principle of the method The Human BCL2L2 solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen. Rigorous validation Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.

Using a PCR-based strategy, an additional protein with life-promoting activity, designated Bcl-w, has been identified. The protein is highly conserved between mouse and human and is encoded by a gene located near the TCRalpha gene on chromosome 14. Bcl-w is expressed in myeloid cell lines but not in T and B lymphocytes, and can be found in a wide range of tissues. An alternative splicing event in exon 4 results in two transcripts. The first, Bcl-w, encodes a protein of 193 amino acids, and the second, Bcl-w/rox, encodes a protein 333 amino acids in length. Therox portion of Bcl-w/rox shows a striking 66% amino acid sequence identity with the Drosophila rox2 protein; however, the Bcl-w/rox transcript may be expressed at very low levels.
