Description

Regulated inhibition of programmed cell death (apoptosis) preserves normal homeostasis and tissue and organ morphogenesis. Aberrations in this process contribute to human diseases and cancer by abnormally prolonging cell viability. Recently, several apoptosis inhibitors related to the baculovirus iap gene have been found in various species, including human. IAP proteins contain one/three Cys/His baculovirus IAP repeats plus a c-terminus RING finger and are thought to block an evolutionary conserved step in apoptosis. Survivin encodes a structurally unique inhibitor of apoptosis (IAP). Survivin expression is turned off during fetal development and is not found in non-neoplastic adult human tissues. Survivin becomes abundantly re-expressed in transformed cells and in all of the most common cancers of lung, colon, pancreas, breast and prostate in vivo. Survivin appears to be situated at the crossroads of cell death and cell division, governing a checkpoint involved in cytokinesis while also suppressing apoptosis. Survivin is also abundantly expressed in brain tissues (astrocytes and some neurons) of adult rats following traumatic brain injury. Survivin has been found co-expressed with NeuN (mature neuronal marker) and PCNA (a cell cycle protein). Survivin might affect regulation of neural cell proliferative responses after brain injury.

Description: This STLALYV monoclonal antibody recognizes human survivin (also known as Birc5). Survivin is a member of the inhibitor of apoptosis (IAP) family that also includes XIAP, c-IAP1, c-IAP2, and NAIP. Survivin functions to inhibit caspase activation, thereby leading to negative regulation of apoptosis. Survivin also plays a critical role in mitosis and cytokinesis where it is expressed only during G2/M and localizes to the mitotic spindle and is found at the cleavage furrow/midplate. Thus, survivin is highly expressed in tumors and in fetal tissue, but is absent in terminally-differentiated cells and non-proliferating cells. Deletion of survivin in developing thymocytes as well as in mature T cells showed that survivin is critical for cell division in lymphoid cells but not for inhibition of survival; the same is true for B lymphocytes.Applications Reported: This STLALYV antibody has been reported for use in immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, microscopy, and immunocytochemistry. (Fluorochrome-conjugated STLALYV is recommended for use in intracellular flow cytometry.).Applications Tested: This STLALYV antibody has been tested by immunocytochemistry of formaldehyde-fixed and permeabilized cells and can be used at less than or equal to 5 μg/mL. This STLALYV antibody has also been tested by immunohistochemistry of formalin-fixed paraffin embedded tissue using high pH antigen retrieval and can be used at less than or equal to 5 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.Purity: Greater than 90%, as determined by SDS-PAGE.Aggregation: Less than 10%, as determined by HPLC.Filtration: 0.2μm post-manufacturing filtered.
