Hbl-2 In Vitro Annexin V-based Apoptosis Assay (FCM)

This assay is to provide Hbl-2-based In Vitro Annexin V-based Apoptosis Assay (FCM) to accelerate our client's oncology projects. The assay will be customized according to the specific requirements. Please contact our scientists to discuss more details.

Hbl-2

Human

The HBL-2 cell line is derived from an AIDS-SNCCL (AIDS-associated small non-cleaved cell lymphoma) patient. After immunophenotypic and molecular genetic analysis, the HBL-2 was established from the original tumor clones. The HBL-2 cell line presents surface immunoglobulin and B-cell restricted markers as well as a phenotype consistent with SNCCL; the cell line also displays clonal immunoglobulin gene rearrangement. The HBL-2 cell line is considered useful as a biological model to study AIDS-associated non-Hodgkin lymphomagenesis (AIDS-NHL) and the impacts of biological, immunological, and viral factors involved.

In Vitro Annexin V-based Apoptosis Assay (FCM)

Localization of phosphatidyl serine, a phospholipid found normally in the internal surface of the plasma membrane, to the external surface of the plasma membrane occurs during apoptosis. Annexin V can bind with phosphatidyl serine and Annexin V conjugates (Annexin V/fluorescein isothiocyanate) are commonly used for detecting apoptosis by FCM.

Detection of Apoptosis Assays

Apoptosis (programmed cell death) plays a vital role in embryonic development, homeostasis, functioning of immune system and wound repair. The ability to evade induction of apoptosis has been used by cancer cells to survive against host defense mechanisms. The molecular mechanisms involved in cancer cell apoptosis have been well documented and it involves certain biochemical events such as DNA fragmentation, chromatin condensation, cell organelle degradation and protein cleavage, etc. The extrinsic and intrinsic (mitochondrial) pathways are the two major pathways involved in apoptosis. With the available techniques and assays, a number of apoptosis inducing agents (natural compounds, synthetic compounds, nano-formulations, peptides and enzymes) in many cancer cells have been identified. Selection of an assay for apoptosis detection is based on factors such as apoptotic pathway, nature of drug, cell type being used and the method of analysis.
