Quantitative Biomarker Assays

Biomarker is a general term for a number of substances including cytokines, growth factors, enzymes, hormones, and neurotransmitters that are secreted by certain cells in the immune system which have an effect on other cells. XpressBio’s quantitative biomarker assays detect a variety of these substances in humans, mice, rats, and other species.

We offer different types of ELISA, such as sandwich, competitive, and indirect ELISA kits. If you are looking for a certain biomarker assay, please contact us. We may have what you’re looking for!
