Invitrogen™ HTRA2 (OMI) Human ELISA Kit

Descripción

The Human HTRA2(OMI) ELISA quantitates Hu OMI in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu OMI. Principle of the method The Human OMI 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.

The inhibitor of apoptosis (IAP) family of proteins regulates programmed cell death triggered by various stimuli. All IAPs have at least one baculovirus IAP repeat (BIR) motif that is essential for their anti-apoptotic activity (1-3). Recently, a serine protease has been isolated, which is released from the mitochondria upon induction of apoptosis by apoptotic stimuli. This protein called Omi/HtrA2 is a mitochondrial protein that binds to IAP (4). Like Smac/DIABLO, the mature Omi protein contains a conserved IAP-binding motif (AVPS) at its N terminus. The deregulated expression of Omi in the cytoplasm of mammalian cells induces apoptosis indicating that Omi could participate in the mitochondrial apoptotic pathway.
