B-Cell Lymphoma 2 (Bcl-2) ELISA Kit

  • Created on the 1 April, 2017.

BACKGROUND

B-cell lymphoma 2 (Bcl-2) belongs to the BCL-2 family of regulatory proteins which are known to be vital in regulating apoptosis by either inhibiting (anti-apoptotic) or by inducing (pro-apoptotic) process. It has been specifically referred to as crucial anti-apoptotic protein and but not a proto-oncogene since it is unable to transduce growth signals. Bcl-2 has the ability to initiate a new gene family that is involved in the regulation of cell death and survival without affecting cell proliferation. This type of precise regulation and maintenance of balance between cell death and cell proliferation in multicellular organisms is very important for tissue homeostasis.

The gene is encoded by a proto-oncogene and it is described as an intracellular membrane associated protein which essentially functions to block programmed cell death. The expression of Bcl-2 has been identified in a number of different epithelial malignancies, hematopoietic cells and non-neoplastic epithelia. The levels of Bcl-2 have been found to be low or even undetectable in endothelial cells. The Bcl-2 gene is known to have a unique function among many mammalian oncogenes since it is involved in the negative regulation of apoptosis, where a decrease in its levels can lead to cell death by apoptosis. On the other hand, overexpression of Bcl-2 is able to protect cells from death, however, this is neither able to lead to tumorgenic transformation of immortalized cells or immortalize normal cells. There have a many homologs of Bcl-2 which have been discovered, some of them are able to function as inhibitors of cell death whereas others can promote the process of apoptosis (i.e. are opposing the function of Bcl-2). Damage occurring to the Bcl-2 gene can lead a number of cancers such as chronic lymphocytic leukemia, melanoma, lung, breast and prostate cancer, it has also been identified as a possible cause for autoimmunity, schizophrenia and resistance to cancer treatments.

INTENDED USE

Human Bcl-2 ELISA kit is a procedure intended for measuring in vitro quantitative amounts of B-cell lymphoma 2 (Bcl-2) in human cell culture supernatant, plasma, serum, cell lysates, tissue homogenates and many other biological fluids. This assay has a minimum sensitivity limit of < 1.15 U/ml.

SENSITIVITY

The minimum detection sensitivity level of a B-cell lymphoma 2 using this human Bcl-2 ELISA kit was 1.15 U/ml. The dynamic assay range for this kit is 2.0 – 700.0 U/ml.
