The interleukin-2 receptor (IL-2R), also known as CD25, is a transmembrane protein, which is up-regulated on activated T-cells, and shed into serum as soluble IL-2R, or sIL-2R. sIL-2R has emerged as an important biomarker.

As laboratories strive to produce faster, more consistent and publication-quality immunoassay data, the need for advanced imaging technology has never been greater.

Human MxA protein (Myxovirus resistance protein 1), the product of the MX1 gene, is a 76-kDa protein consisting of 662 amino acid residues and belonging to the dynamic superfamily of large GTPase. MxA protein plays an important role in antiviral activity in cells against a wide variety of viruses.
