Introduction
The RayBio® Monkeypox Virus (MPXV) E8L ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of MPXV E8L in serum, plasma (collect plasma using EDTA as an anticoagulant. Heparin or citrate are not recommended in this assay), and cell culture supernatants. This assay employs an antibody specific for MPXV E8L coated on a 96-well plate. Standards and samples are pipetted into the wells and MPXV E8L present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-MPXV E8L antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of MPXV E8L bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Customize This Monkeypox Virus (MPXV) E8L ELISA
We manufacture our ELISAs in-house, so we can build a custom version for your study.
- Post-translational modifications (PTMs): Detect modified E8L / OPG105, including phosphorylation, acetylation, S-nitrosylation, S-acylation, oxidation, lactylation, sumoylation, ubiquitination, nitration, carbamylation, and more
- Sample types: Validation in your matrix using samples you provide, such as CSF, urine, saliva, lysates, or exosomes
- Also available: More sensitive platforms such as Simoa® and NexaTag®, multiplex panels, bulk lots, and other species when suitable reagents exist
Feasibility varies by target and modification, and we’ll tell you upfront what’s achievable.
