It belongs the immunoglobulin superfamily. BTN1A1 acts as a specific membrane-associated receptor for the association of cytoplasmic droplets with the apical plasma membrane. It is localized to the major histocompatibility complex (MHC) class I region of 6p. It may have arisen relatively recently in evolution by the shuffling of exons between 2 ancestral gene families. It is shown that BTN1A1 inhibits the proliferation of CD4 and CD8 T-cells activated by anti-CD3 antibodies, T-cell metabolism and IL2 and IFNG secretion.\u003c\/p\u003e\n\n\u003cp\u003eSequence: Ala27-Arg242\u003c\/p\u003e\n\n\u003cp\u003ePurity: \u0026gt; 95 % as determined by reducing SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.2 μm filtered solution of 20mM PB, 150mM NaCl, pH 7.2.\u003cbr\u003e\nNormally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.\u003cbr\u003e\nPlease refer to the specific buffer information in the printed manual.\u003c\/p\u003e\n\n\u003cp\u003eReconstitution: Please refer to the printed manual for detailed information.\u003c\/p\u003e\n\n\u003cp\u003eEndotoxin: \u0026lt; 1.0 EU per μg of the protein as determined by the LAL method.\u003c\/p\u003e\n\n\u003cp\u003eCalculated MW: 25.0 kDa\u003c\/p\u003e\n\n\u003cp\u003eObserved MW: 33 kDa\u003c\/p\u003e\n\n\u003cp\u003eStorage: Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80℃.
