Glycosaminoglycans (GAGs) are large complex carbohydrate molecules that interact with a wide variety of proteins involved in physiological and pathological processes. GAGs are also known as mucopolysaccharides due to their viscous, lubricating properties, as found in mucous secretions. GAGs are found on all animal cell surfaces in the extracellular matrix (ECM), and some are known to bind and regulate certain proteins, including chemokines, cytokines, growth factors, morphogens, enzymes and adhesion molecules.

GAGs are linear, sulphated, negatively charged polysaccharides that have molecular weights of approximately 10–100 kDa. GAGs can be divided into two main types. Non‐sulphated GAGs include hyaluronic acid (HA), whereas sulphated GAGs include chondroitin sulphate (CS), dermatan sulphate (DS), keratan sulphate (KS), heparin and heparan sulphate (HS).

GAGs play an important role in cell signaling and development, angiogenesis, axonal growth, tumour progression, metastasis and anti‐coagulation. Uncontrolled progenitor cell proliferation leads to malignant tissue transformation and cancer. GAGs and proteoglycans (PGs) are believed to play a critical role in cell proliferation, acting as co‐receptors for growth factors of the fibroblast growth factor (FGF) family.

PGs are composed of a core protein to which one or more GAG chains are covalently attached. Examples of large PGs are aggrecan, the major PG in cartilage, and versican, which is present in numerous adult tissues such as blood vessels and skin. PGs are known to have a variety of functions, dependent on type and in vivo location, and have important roles in invertebrate and vertebrate development, maintenance, and tissue repair. Many biologically potent small proteins can bind GAG chains as a major part of their function in the ECM, at the cell surface, and also in some intracellular locations. Thus, PGs have become a major focus in research on many diseases.

Fibronectin is a widely used broad range natural cell attachment factor. This product has been purified from human plasma where it is found as a dimer and has a size of 440-500 kDa with two similar subunits (220-250 kDa ) linked by two disulfide bonds. Fibronectin’s primary function is related to cell adhesion and attachment to extracellular matrix. Certain domains of Fibronectin have been found to play important roles that involve interactions with collagen, heparin and other cell surface glycosaminoglycans (GAGs). Fibronectin is ideal for coating of surfaces and is typically used at a concentration of 1-5 ug/cm2 . It is provided in user-friendly packaging for use and storage. Fibronectin is sterile filtered and is supplied as a ready to use solution after thawing and concentration adjustment. This product is shipped separately on dry ice.

Polyethylene glycol (PEG) is a condensation polymer of ethylene oxide and water.
Polyethylene Glycol has been used in the precipitation of proteins, as a fusing agent in enhancing the effect of macrophages on hybridoma, in the separation and purification of biomolecules and in induction of cell hybridization.
PEG's are susceptible to oxidative degradation in the presence of air. Minimizing the exposure of PEG to elevated temperatures and/or exposure to oxygen, or addition of an antioxidant can limit the amount of degradation. PEGs do not hydrolyze or deteriorate upon storage. PEGs do not support the growth of molds.
