Human IL10RB / CRFB4 ELISA Pair Set

DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Materials provided
Capture Ab:0.5 mg/mL of mouse anti-IL10RB monoclonal antibody. Dilute to a working concentration of 2.0 μg/mL in CBS before coating.
Detection Ab:0.7 mg/mL rabbit anti-IL10RB polyclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to a working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 110 ng of recombinant IL10RB. Reconstitute standard powder 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 5000 pg/mL is recommended.
The minimum detectable dose of human IL10RB / CRFB4 was determined to be approximately 78.125 pg/ml. This is defined as at least three times standard deviations above the mean optical density of 10 replicates of the zero standard.
Principle of the product
The human IL10RB / CRFB4 ELISA Pair Set is for the quantitative determination of human IL10RB / CRFB4.
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 IL10RB /CRFB4 coated on a 96-well plate. Standards and samples are added to the wells,and any IL10RB / CRFB4 present binds to the immobilized antibody. The wells arewashed and a horseradish peroxidase conjugated rabbit anti-IL10RB polyclonalantibody is then added, producing an antibody-antigen-antibody "sandwich". Thewells are again washed and TMB substrate solution is loaded, which producescolor in proportion to the amount of IL10RB / CRFB4 present in the sample. Toend the enzyme reaction, the stop solution is added and absorbances of themicrowell are read at 450 nm.
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: Protect it from prolonged exposure to light. Aliquot and store at -20℃ to -80℃ and for up to 6 months from date of receipt. Avoid repeated freeze-thaw cycles.
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.

Interleukin 10 receptor, beta subunit (IL10RB/IL-10RB) also known as Cytokine receptor family 2 member 4, Interleukin-10 receptor subunit 2, and cytokine receptor family II, member 4, is a subunit for the interleukin-10 receptor. IL10RB/IL-10RB belongs to the cytokine receptor family. It is an accessory chain essential for the active interleukin 10 receptor complex. Coexpression of this and IL10RA proteins has been shown to be required for IL10-induced signal transduction. Defects in IL10RB/IL-10RB are the cause of inflammatory bowel disease type 25 (IBD25). It is a chronic, relapsing inflammation of the gastrointestinal tract with a complex etiology. It is subdivided into Crohn disease and ulcerative colitis phenotypes. Crohn disease may affect any part of the gastrointestinal tract from the mouth to the anus, but most frequently it involves the terminal ileum and colon. Bowel inflammation is transmural and discontinuous; it may contain granulomas or be associated with intestinal or perianal fistulas. In contrast, in ulcerative colitis, the inflammation is continuous and limited to rectal and colonic mucosal layers; fistulas and granulomas are not observed. Both diseases include extraintestinal inflammation of the skin, eyes, or joints.
