CD48 antigen (CD48)

Links to databases

 

CD48 antigen, also known as B-lymphocyte activation marker (BLAST-1) or signaling lymphocytic activation molecule 2 (SLAMF2) is a member of the CD2 subfamily of the immunoglobulin superfamily. CD48 is found on the surface of several types of immune cells, endothelial cells and dendritic cells, where it is involved in activation and differentiation pathways. CD48 was the first B-cell-specific cellular differentiation antigen to be identified in transformed B lymphoblasts.

Sample type

Recommended sample types are human EDTA plasma and serum. A range of additional sample types are compatible with the technology (PEA), including citrate plasma, heparin plasma, cerebrospinal fluid, (CSF), tissue and cell lysates, fine needle biopsis, microdialysis fluid, cell culture media, dried blood spots, synovial fluid, saliva, plaque extract and microvesicles. Please note that protein expression levels are expected to vary in different sample types. Certain assays are differentially affected by interfering substances such as hemolysate. Download any of our Data Validation documents or contact support@olink.com for more information.

NOTE: The calibrator curve below shows the performance of the assay with the estimated sensitivity and dynamic range parameters indicated. These curves are generated during the assay validation process using recombinant antigens. Please note that when analyzing biological samples the data generated will be given in the form of relative quantification (NPX values) and cannot be converted to absolute protein concentrations. For more info about NPX measurements, please visit our FAQ page.

Precision

    • Within run precision Coefficient of Variation (CV)
    • 7%
    • Between run precision Coefficient of Variation (CV)
    • 14%

Precision (repeatability) is calculated from linearized NPX values over LOD.
