The Anti-MPXV E8L Human IgM ELISA Kit (SKU: GXEL00307) is a quantitative indirect ELISA for the measurement of Anti-MPXV E8L Human IgM in plasma, serum. The assay has a detection range of 0.78 - 50 ng/mL and a sensitivity of 0.21 ng/mL.
This assay employs the quantitative indirect enzyme immunoassay technique. Recombinant Monkeypox Virus E8L has been pre-coated onto a microplate. Standards or samples are pipetted into the wells and any Anti-MPXV E8L Human IgM present is bound by the immobilized protein. After washing away any unbound substances, a HRP labeled Goat Anti-Human IgM antibody is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of Anti-MPXV E8L Human IgM bound in the initial step. The color development is stopped and the intensity of the color is measured.

Step
Procedure
1
Preparation: Bring all reagents and samples to room temperature and prepare reagents, working standards and samples as directed. Assay all standards and samples in duplicate.
2
Standard & Sample Incubation: Add 100 µL standard or samples to each well; incubate for 1 hour at 37°C. Wash 3 times with Wash Buffer (300 µL).
3
Detection: Add 100 µL of Detection A (working solution) to each well; incubate for 30 minutes at 37°C. Wash 5 times with Wash Buffer (300 µL).
4
Color Development: Add 100 µL of Color Reagent to each well; incubate for 15 minutes at 37°C; protect from light.
5
Stop & Read: Add 50 µL of Stop Solution to each well, then read the optical density at 450 nm within 10 minutes (correction 630 nm or 620 nm).
Sample Type
Protocol
Serum
Use a serum separator tube (SST) and allow samples to clot for 30 minutes at room temperature before centrifugation for 15 minutes at 1000 x g. Remove serum and assay immediately or aliquot and store samples at ≤ -20°C. Avoid repeated freeze-thaw cycles.
Plasma
Collect plasma using EDTA, heparin, or citrate as an anticoagulant. Centrifuge for 15 minutes at 1000 x g within 30 minutes of collection. Assay immediately or aliquot and store samples at ≤ -20°C. Avoid repeated freeze-thaw cycles.
