|1.0 mg/mL of rabbit anti-mouse BST1 monoclonal antibody, Dilute to a working concentration of 2 μg/mL in CBS before coating. (Catalog: # 50319-R213)|
|0.5 mg/mL rabbit anti-mouse BST1 polyoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.|
|Each vial contains 65 ng of recombinant mouse BST1. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve usi ng 2-fold serial dilutions in sample dilution buffer, and a high standard of 2 ng/mL is recommended.|
|The minimum detectable dose of Mouse CD157 / BST1 was determined to be approximately 31.25 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.|
|The Mouse CD157 / BST1 ELISA Pair Set is for the quantitative determination of Mouse CD157 / BST1.|
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 CD157 / BST1 coated on a 96-well plate. Standards and samples are added to the wells, and any CD157 / BST1 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-CD157 / BST1 polyclonal antibody is then added, producing an antibody-antigen-antibody "sandwich". The wells are again washed and TMB substrate solution is loaded, which produces color in proportion to the amount of CD157 / BST1 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
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.
