Human DC-SIGN / CD209 ELISA Pair Set

DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human CD209 Materials provided
Capture Ab:0.2 mg/mL of mouse anti-CD209 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 2 μg/mL in PBS before coating.
Detection Ab:0.2 mg/mL rabbit anti-CD209 monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-Protector, pH 7.4). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 165 ng of recombinant CD209. 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 using 2-fold serial dilutions in sample dilution buffer, and a high standard of 1.5 ng/mL is recommended.
Human CD209 Specificity
Human CD209 Sensitivity
The minimum detectable dose of Human DC-SIGN / CD209 was determined to be approximately 23.4375 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 CD209 Principle of the product
The Human DC-SIGN / CD209 ELISA Pair Set is for the quantitative determination of Human DC-SIGN / CD209.
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 DC-SIGN / CD209 coated on a 96-well plate. Standards and samples are added to the wells, and any DC-SIGN / CD209 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-DC-SIGN / CD209 monoclonal 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 DC-SIGN / CD209 present in the sample. To end the enzyme reaction, the stop solution is added and absorbances of the microwell are read at 450 nm.
Human CD209 Storage
Capture Antibody: Aliquot and store at -20℃ to -80℃ for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.
Detection Antibody: Store at 4℃ and protect it from prolonged exposure to light for up to 6 months from date of receipt. DO NOT FREEZE!
Standard: Store lyophilized Standard at -20℃ to -80℃ for up to 6 months from date of receipt. Aliquot and store the reconstituted Standard at -80℃ for up to 1 month. Avoid repeated freeze-thaw cycles.

DC-SIGN/CD209 Background

Dendritic cell (DC)-specific intercellular adhesion molecule 3 (ICAM-3) grabbing nonintegrin (DC-SIGN), also known as CD209, is a type II transmembrane protein on DCs with a C-type lectin extracellular domain, is capable of binding ICAM-3 on resting T cells in the secondary lymphoid organs, providing the initial contact between these cells during the establishment of cell-mediated immunity. It is not only a pattern recognition receptor but implicated in immunoregulation of DCs. It has important role in mediating DC adhesion, migration, inflammation, activating primary T cell, triggering immune response and participating in immune escape of pathogens and tumors. DC-SIGN also mediates capture and internalization of viral, bacterial, and fungal pathogens by dendritic cells, such as HIV-1, Ebola virus, cytomegalovirus, Dengue virus, and hepatitis C virus. DC-SIGN is unique in that it regulates adhesion processes, such as DC trafficking and T-cell synapse formation, as well as antigen capture. Moreover, even though several C-type lectins have been shown to bind HIV-1, DC-SIGN does not only capture HIV-1 but also protects it in early endosomes allowing HIV-1 transport by DC to lymphoid tissues, where it enhances trans infection of T cells.
