CD53 does not overlap with CD82. A: B cell membrane sheets double stained for CD82(Rab) (red) and CD82(Mo) (green) were imaged by STED microscopy. Scale bars: 5 μm in whole sheets and 1 μm in zoomed images. Graph: intensity profiles of CD82(Rab) (red curves) and CD82(Mo) (filled green) as depicted in the corresponding images. B: B cells membrane sheets double stained for CD82(Rab) (red) and CD53(Mo) (green) were imaged by STED microscopy. Scale bars: 5 μm in whole sheets and 0.5 μm in zoomed images. Graphs: intensity profiles of CD82 (red line) and CD53 (filled green) as depicted in the corresponding images.

Rabbit anti Human CD82 antibody recognises the carboxy-terminal region of human CD82, also known as KAI1, SAR2 and TSPAN27. CD82 is a ~30 kDa multi-pass transmembrane glycoprotein belonging to the tetraspanin (TM4SF) family.
CD82 acts as a cancer metastasis suppressor protein (Feng et al.2015), while ubiquitously expressed at moderate to high levels in many normal tissues, its expression is down regulated during tumour progression. Loss of CD82 and p53 is correlated with poor prognosis for patients with prostate and other forms of cancer (Liu et al. 2006).
CD82 interacts with CD234 (DARC). Tumour cells dislodged from the primary tumour and expressing CD82 interact with CD234 expressed on vascular cells, transmitting a senescent signal to the tumour cells (Tsai et al 2011). Tumor cells that have lost CD82 expression can proliferate and potentially give rise to metastases (Miranti 2009).
Two isoforms of CD82 may be generated by alternative splicing. The c-terminal region is not affected and thus Rabbit anti Human CD82 antibody is expected to recognize both isoforms of human CD82 (UniProt: P27701).
