SARS-CoV-2 IgM Antibody ELISA Kit

Catalog No. ABIN6952526

Product Details

Target: SARS-CoV-2 IgM Antibody

Reactivity: Human, SARS Coronavirus-2 (SARS-CoV-2)

Detection Method: Colorimetric

Method Type: Sandwich ELISA

Application: ELISA

Purpose: Enzyme Linked Immunosorbent Assays (ELISA) for the qualitative detection of the COVID-19 IgM in human serum.

Sample Type: Serum

Analytical Method: Qualitative

Characteristics: gM is first immunoglobulin to be produced in response to an antigen and will be primarily detectable during the early onset of the disease. IgM antibodies begin to show positive after 3-5 days of onset.

Components:

• COVID-19 IgM coated Microplate
• COVID-19 IgM Sample Diluent
• HRP labeled COVID-19 Antigen
• ELISA Wash Concentrate
• ELISA HRP Substrate
• ELISA Stop Solution
• COVID-19 IgM Negative Control
• COVID-19 IgM Positive Control

Material not included:

• Precision single channel pipettes capable of delivering 10 µL, 25 µL, 100 µL, and 1000 µL, etc.
• Repeating dispenser suitable for delivering 100 µL.
• Disposable pipette tips suitable for above volume dispensing.
• Disposable 12 x 75 mm or 13 x 100 glass tubes.
• Disposable plastic 1000 mL bottle with caps.
• Aluminum foil.
• Deionized or distilled water.
• Plastic microtiter well cover or polyethylene film.
• ELISA multichannel wash bottle or automatic (semi-automatic) washing system.
• Spectrophotometric microplate reader capable of reading absorbance at 450 nm.

Application Details

Application Notes: National Health Commission of the People's Republic of China states that IgM antibodies begin to show positive after 3-5 days of onsett of COVID-19

Plate: Pre-coated

Protocol: Assay controls and samples are added to the microtiter wells of a microplate that was coated with a anti-human IgM specific antibody. After the first incubation period, the unbound protein matrix is removed with a subsequent washing step. A horseradish peroxidase (H labeled recombinant COVID-19 antigen is added to each well. After an incubation period, an immunocomplex of "Anti-hIgM antibody COVID-19 IgM antibody - HRP labeled COVID-19 antigen" is formed if there is novel coronavirus IgM antibody present in the tested materials. The unbound tracer antigen is removed by the subsequent washing step. HRP-labeled COVID-19 antigen tracer bound to the well is then incubated with a substrate solution in a timed reaction and then measured in a spectrophotometric microplate reader. The enzymatic activity of the tracer antigen bound to the coronavirus IgM on the wallof the microtiter well is proportional to the amount of the coronavirus IgM antibody level in the tested materials.

Restrictions: For Research Use only
