HeMoStep Kit

Most reliable method to quantify blood contamination in CSF.

Now, there is an Easy Step ELISA Kit to solve your scientific research troubles!

One-step method EasyStep principle

The kit adopts the sandwich method principle. Coat the specific antibody in a 96-well microplate, add the standard/sample, so that the protein in the standard or the protein in the sample binds to the antibody solid-phased on the microplate, and then add the HRP-coupled antibody , after thoroughly washing the unbound HRP-conjugated antibody, add TMB substrate to develop color. TMB is converted into blue under the catalysis of peroxidase and into the final yellow under the action of acid. The depth of color is positively correlated with the target protein in the sample. Use a microplate reader to measure the absorbance (OD value) at a wavelength of 450 nm, and calculate the sample concentration by drawing a standard curve.

Monkeypox Virus (MPXV) IgG ELISA Kit

Monkeypox virus (MPV) is an orthopoxvirus that causes a disease with symptoms similar, but less severe, to smallpox. While smallpox was eradicated in 1980, monkeypox continues to occur in countries of central and west Africa. Two distinct clade are identified: the west African clade and the Congo Basin clade, also known as the central African clade. In May 2022, multiple cases of monkeypox were detected in several non-endemic countries, making it urgent to further understand the epidemiology, source of infection and mode of transmission of this disease.

Monkeypox virus (MPV) is a double-stranded DNA virus belonging to orthopoxviruses of the Poxviridae family. It is one of the human orthopoxviruses, including variola (VACV), vaccinia (CPX) and vaccinia (VACV) viruses. Monkeypox virus is about 200-400 nm in size, brick or oval in shape, with stable DNA structure, which can repair itself when mutation occurs.


Intended use

This ELISA kit applies to the in vitro qualitative determination of Monkeypox Virus (MPXV) IgG in human serum and plasma.


  1. Cut Off(C.O.) = 2.1 × Negative Control(NC) average A450.

When NC average A450 < 0.05, calculate it as 0.05. While 0.05 ≤ NC average A450 ≤ 0.15, calculate it as the actual value.

l  Positive result: Sample absorbance ≥ Cut Off

l  Negative result: Sample absorbance < Cut Off

  1. Intra-CV: CV%<8%

 Inter-CV: CV%<10%


The unopened kit can be stable for 6 months at 2-8℃. After opening the kit, keep the reagents according to the manual.
