Western Blotting (WB), ELISA, Immunohistochemistry (Paraffin-embedded Sections) (IHC (p))
Purpose
Rabbit Anti-Human CD253
Specificity
DS-PB-02541 is specific for human CD253, otherwise known as TRAIL or Apo2L, a 281 amino acid type II transmembrane glycoprotein and member of the tumor necrosis factor superfamily, which induces apoptosis in tumor 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-tumor and anti-viral cytotoxicity.
