Human NTB-A, His Tag (NTA-H52Ha) is expressed from human 293 cells (HEK293). It contains AA Gln 22 - Met 226 (Accession # Q96DU3-1).
Predicted N-terminus: Gln 22
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 25.0 kDa. The protein migrates as 35-45 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
Less than 1.0 EU per μg by the LAL method.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

Human NTB-A, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
The SLAM family of receptors is composed of six members named SLAM (CD150); 2B4 (CD244); Ly-9 (CD229); CD84; natural killer, T and B cell antigen (NTB-A; Ly108 in the mouse. Most, if not all,immune cell types express more than one SLAM family receptor. All six SLAM-related genes are located within a 400–500 kilobase (kb) genomic segment on chromosome 1 in humans and mice. This feature implies that the genes that encode the SLAM family were created by serial gene duplication.
