CD57 natural killer cell marker IVD, antibody

This category includes antibodies designed to detect the CD57 antigen, a surface marker found on natural killer (NK) cells and certain T-cell subsets. These reagents are used in laboratory settings to identify and quantify CD57-positive cells in clinical specimens such as blood or tissue samples, aiding in the assessment of immune function and the diagnosis of certain immunological conditions or malignancies.

Devices in this category are in vitro diagnostic (IVD) reagents regulated as immunological assays. They are supplied as standalone antibodies or as part of staining kits for use in techniques like immunohistochemistry (IHC) or flow cytometry, and their regulatory status depends on the intended use and jurisdiction, with individual products requiring appropriate conformity assessment before market placement.
