Description: The 5D10 monoclonal antibody reacts with the murine MULT-1 (Murine ULBP-Like Transcript 1). MULT-1 is a type I transmembrane protein with two Ig-like domain and is one of the known murine NKG2-D ligands that include RAE1 molecules (alpha, beta, epsilon, gamma and delta) and H60. MULT-1 is a high affinity ligand for NKG2D.Expression of NKG2-D ligands is low or absent on normal adult tissues. However, stressed or transformed cells express NKG2-D ligand and can activate NK cell tumoricidal activity. Until now, the expression of NKG2-D ligands has been mainly studied with NKG2-D tetramers recognizing all NKG2-D ligands.
