Human CD157 / BST1 ELISA Pair Set

DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human CD157/BST1 Materials provided
Capture Ab:0.5 mg/mL of mouse anti-BST1 monoclonal antibody. Dilute to a working concentration of 1 μg/mL in CBS before coating.
Detection Ab:0.3 mg/mL of biotinylated rabbit anti-BST1 polyclonal antibody. Dilute to a working concentration of 0.2 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 15 ng of recombinant BST1. Reconstitute with 1 mL detection antibody dilution buffer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 1 ng/mL is recommended.
Streptavidin-HRP:50 μL of streptavidin conjugated to horseradish-peroxidase. 1:2000 Dilution in detection antibody dilution buffer before use.
Human CD157/BST1 Specificity
Human CD157/BST1 Sensitivity
The minimum detectable dose of human BST-1 / CD157 was determined to be approximately 15.6 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
Human CD157/BST1 Principle of the product
The human BST-1 / CD157 ELISA Pair Set is for the quantitative determination of human BST-1 / CD157.
This ELISA Pair Set contains the basic components required for the development of sandwich ELISAs.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for BST-1 / CD157 coated on a 96-well plate. Standards and samples are added to the wells, and any BST-1 / CD157 present binds to the immobilized antibody. The wells are washed and a biotinylated rabbit anti-BST-1 / CD157 polyclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". To produces color in proportion to the amount of BST-1 / CD157 present in the sample strepavidin-HRP and TMB substrate solution are loaded. The absorbances of the microwell are read at 450 nm.

CD157/BST1 Background

The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. CD157, also known as ADP-ribosyl cyclase 2, is an ectoenzyme sharing several characteristics with ADP-ribosyl cyclase CD38. CD157 was originally identified as a bone marrow stromal cell molecule (BST-1) with a glycosylphosphatidylinositol (GPI) anchor to bind to the cell surface. CD157 is prevalently expressed by cells of the myeloid lineage. CD157 could act as a receptor with signal transduction capability. Further, it regulates calcium homeostasis and promotes polarization in neutrophils and mediates superoxide (O2−) production in the human U937 myeloid line.
