Human CD146 / MCAM / MUC18 ELISA Pair Set

DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Human CD146/MCAM Materials provided
Capture Ab:0.5 mg/mL of mouse anti-CD146 monoclonal antibody. Dilute to a working concentration of 2 μg/mL in CBS before coating.
Detection Ab:0.5 mg/mL rabbit anti-CD146 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use
Standard:Each vial contains 25 ng of recombinant CD146. 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.
Human CD146/MCAM Specificity
Human CD146/MCAM Sensitivity
The minimum detectable dose of human CD146 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..
Human CD146/MCAM Principle of the product
The human CD146 ELISA Pair Set is for the quantitative determination of human CD146.
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 CD146(MCAM / MUC18) coated on a 96-well plate. Standards and samples are added tothe wells, and any CD146 present binds to the immobilized antibody. The wellsare washed and a horseradish peroxidase conjugated rabbit anti-CD146 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 CD146 present in the sample. To end theenzyme reaction, the stop solution is added and absorbances of the microwellare read at 450 nm.
Human CD146/MCAM 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: 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.
CD146/MCAM Background

The CD146 antigen, also known as melanoma cell adhesion molecule (MCAM) and MUC18, is an integral membrane glycoprotein belonging to the immunoglobulin superfamily. CD146 contains the characteristic immunoglobulin-like domains (V-V-C2-C2-C2), a transmembrane region and a short cytoplasmic tail. The CD146 expression is detected in endothelial cells in vascular tissue throughout the body, and plays a role in cell adhesion, as well as in cohesion of the endothelial monolayer at intercellular junctions in vascular tissue. As a Ca2+-independent cell adhesion molecule involved in heterophilic cell to cell interactions and a surface receptor, CD146 triggers tyrosine phosphorylation of FYN and PTK2 and subsequently induced signal transduction, proteolysis, or immune recognition. This protein is also expressed predominantly on metastatic lesions and advanced primary tumours, and thus has been suggested to play an important role in tumour progression and the development of metastasis in certain human carcinomas.
