This product, an anti CD253 antibody, recognizes human CD253. CD253, otherwise known as TRAIL or Apo2L, is a 281 amino acid type II transmembrane glycoprotein and member of the tumour necrosis factor superfamily, which induces apoptosis in tumour and transformed cells, but not normal cells.
Activation of apoptosis by CD253 occurs through binding to the death-signaling receptors DR4 (TRAILR1) and DR5 (TRAILR2), leading to formation of the death-inducing signaling complex (DISC) and the triggering of a proteolytic caspase cascade. There are however decoy receptors known as DcR1 (TRAILR3) and DcR2 (TRAILR4) which competitively bind to CD253 and are unable to initiate apoptosis.
CD253 also plays a role in immune surveillance, acting as a mediator of monocyte, NK cell, dendritic cell and T cell anti-tumour and anti-viral cytotoxicity.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Storage
Prior to reconstitution store at +4oC.
After reconstitution store at -20oC.
Storage in frost-free freezers is not recommended. This product should be stored undiluted. Avoid repeated freezing and thawing as this may denature the antibody. Should this product contain a precipitate we recommend microcentrifugation before use.
Shelf Life
12 months from date of reconstitution.
Antiserum Preparation
Antisera to human CD253 were raised by repeated immunisations of rabbits with highly purified antigen. Purified IgG prepared by affinity chromatography.
Anti human CD253:biotin conjugate may be used in a direct ELISA or as the detection reagent in a sandwich ELISA withanti human CD253:purified(AHP1215) as the capture reagent andrecombinant human CD253(PHP125) as the standard.
