DatasheetReviewsRelated ProductsProtocols
Human ERBB2 Materials provided
Capture Ab:1 mg/mL of rabbit anti-Human HER2 / ErbB2 / CD340 monoclonal antibody (in PBS, pH 7.4). Dilute to a working concentration of 1 μg/mL in PBS before coating.
Detection Ab:0.1 mg/mL of rabbit anti-Human HER2 / ErbB2 / CD340 monoclonal antibody conjugated to horseradish-peroxidase (HRP) (in PBS, 50 % HRP-Protector, pH 7.4, store at 4℃). Dilute to working concentration of 0.5 μg/mL in detection antibody dilution buffer before use.
Standard:Each vial contains 110 ng of recombinant Human HER2 / ErbB2 / CD340. 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 1500 pg/mL is recommended.
Human ERBB2 Sensitivity
The minimum detectable dose of Human HER2 / ErbB2 / CD340 was determined to be approximately 24 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 ERBB2 Principle of the product
The Human HER2 / ErbB2 / CD340 ELISA Pair Set is for the quantitative determination of Human HER2 / ErbB2 / CD340.
The Sino Biological ELISA Pair Set is a solid phase sandwich ELISA (Enzyme-Linked Immunosorbent Assay). It utilizes a monoclonal antibody specific for Human HER2 / ErbB2 / CD340 coated on a 96-well plate. Standards and samples are added to the wells, and any Human HER2 / ErbB2 / CD340 present binds to the immobilized antibody. The wells are washed and a horseradish peroxidase conjugated rabbit anti-Human HER2 / ErbB2 / CD340 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 Human HER2 / ErbB2 / CD340 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 ERBB2 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.

HER2/ErbB2 Background

Human epidermal growth factor receptor 2 (HER2), also known as ErbB2, NEU, and CD340, is a type I membrane glycoprotein, and belongs to the epidermal growth factor (EGF) receptor family. HER2 protein cannot bind growth factors due to the lacking of ligand binding domain of its own and autoinhibited constitutively. However, HER2 forms a heterodimer with other ligand-bound EGF receptor family members, therefore stabilizes ligand binding and enhances kinase-mediated activation of downstream molecules. HER2 plays a key role in development, cell proliferation and differentiation. HER2 gene has been reported to associate with malignancy and a poor prognosis in numerous carcinomas, including breast, prostate, ovarian, lung cancers and so on.
