|1.0 mg/mL of mouse anti-CD40 monoclonal antibody. Dilute to a working concentration of 2.0 μg/mL in CBS before coating|
|0.5 mg/mL rabbit anti-CD40 monoclonal 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 20 ng of recombinant CD40. 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 250 pg/mL is recommended|
|The minimum detectable dose of human CD40 / TNFRSF5 was determined to be approximately 3.9 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 human CD40 / TNFRSF5 ELISA Pair Set is for the quantitative determinationof human CD40
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 CD40 / TNFRSF5 coated on a 96-well plate. Standardsand samples are added to the wells, and any CD40 / TNFRSF5present binds to the immobilized antibody. The wells are washed and ahorseradish peroxidase conjugated rabbit anti-CD40 / TNFRSF5 monoclonal antibody is then added, producing anantibody-antigen-antibody "sandwich". The wells are again washed and TMBsubstrate solution is loaded, which produces color in proportion to the amountof CD40 / TNFRSF5 present in the sample. To end theenzyme reaction, the stop solution is added and absorbances of the microwellare read at 450 nm.

CD40, also known as TNFRSF5, is a member of the TNF receptor superfamily which are single transmembrane-spanning glycoproteins. CD40 protein plays an essential role in mediating a broad variety of immune and inflammatory responses including T cell-dependent immunoglobulin class switching, memory B cell development, and germinal center formation. CD40 protein is expressed in B cells, dendritic cells, macrophages, endothelial cells, and several tumor cell lines. Defects in CD40 result in hyper-IgM immunodeficiency type 3 (HIGM3). In addition, CD40/CD40L interaction is found to be necessary for amyloid-beta-induced microglial activation, and thus is thought to be an early event in Alzheimer disease pathogenesis.
