AMSBIO has announced a number of new and unique kits for proteoglycan research. Glycosaminoglycans (GAGs) are polysaccharides consisting of repeated dimers. All but hyaluronic acid (HA) possess sulfate bases, and exist in living organisms in the form of proteoglycans. Sulfated GAGs play important roles in the functions of a number of tissues. A new Sulfated GAG Quantitation Kit allows easy quantification of sulfated GAGs in tissues such as cartilage, cultured chondrocytes, and chondrocyte culture solution, and is ideal for use in cartilage research and other fields. Based on a colorimetric determination method, using 1,9-dimethylmethylene blue (DMMB), the new kit is capable of measuring amounts in the 2.5-80 µg/ mL range within a wide standard curve. Provided in a standard 96-well plate format that can be stored for up to one year, the kit facilitates simple, simultaneous processing of multiple samples.
