WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.

KAI1 was initially identified from a T-cell activation study as a four-transmembrane protein that plays an accessory role in T-cell activation, and was later determined to act as a cancer metastasis suppressor gene.This protein is ubiquitously expressed at moderate to high levels in most tissues, but its expression is downregulated during tumor progression.The loss of KAI1 and p53 is associated with poor survival for prostate and other cancer patients.Recently, KAI1 was found to interact with DARC, the Duffy antigen for chemokines using a yeast two hybrid screen.It is thought that tumor cells dislodged from the primary tumor and expressing KAI1 interact with DARC proteins expressed on vascular cells, transmitting a senescent signal to the tumor cells, while tumor cells that have lost KAI1 expression can proliferate and potentially give rise to metastases.At least two isoforms of KAI1 are known to exist. Synonyms: CD82 antigen, tetraspanin-27, Tspan-27, suppressor of tumorgenicity-6
