Keratan sulfate (KS) ELISA Kit

Designed by Assay Genie for research use, this colorimetric competitive ELISA kit enables the quantification of keratan sulfate in biological samples. Keratan sulfate is a critical component of proteoglycans found in connective tissues, cartilage, and the cornea, and changes in its levels have been linked to various diseases and conditions, making it an important biomarker for research and diagnostic purposes.

The kit is suitable for use with serum, plasma, and cell culture supernatant samples, with reactivity described as universal/general. Manufacturer specifications indicate the assay covers a working range of 0.312-20 ng/mL.

The procedure follows a standard competitive ELISA workflow: standards, blanks, or samples are added to the microplate wells along with detection reagents, followed by incubation at 37°C, repeated washing, substrate addition, and reading of the optical density at 450 nm using a microplate reader.
