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.

Tyrosine hydroxylase (TH) is the rate-limiting enzyme in the synthesis of the catecholamines dopamine, epinephrine and norepinephrine. Therefore the regulation of the TH enzyme represents the central means for controlling the synthesis of these important catecholamines. FUNCTION: Plays an important role in the physiology of adrenergic neurons. CATALYTIC ACTIVITY: L-tyrosine + tetrahydrobiopterin + O2 = 3,4-dihydroxy-L-phenylalanine + 4a-hydroxytetrahydrobiopterin. COFACTOR: Fe(2+) ion. ENZYME REGULATION: Phosphorylation leads to an increase in the catalytic activity. PATHWAY: Catecholamine biosynthesis; first step. SUBUNIT: Homotetramer. PTM: In vitro, phosphorylation of Ser-19 increases the rate of Ser-40 phosphorylation, which results in enzyme opening and activation. SIMILARITY: Belongs to the biopterin-dependent aromatic amino acid hydroxylase family. The presence of different DNA sequences at the TH locus confers susceptibility to various disorders of the brain including manic-depression and schizophrenia. Parkinson's disease is also considered a TH deficiency as low dopamine levels are a consistent neurochemical abnormality.

PNGase F PRIME is a mutant recombinant PNGase F cloned from Flavobacterium meningosepticum and expressed and purified from E. coli. The proprietary changes made to PNGase F have been shown to have unique characteristics when compared to other commercially-available sources of PNGase F. Data generated by independent labs shows that PRIME works on native glycoproteins and serum glycoproteins in minutes at room temperature. Glycan analysis of the digestion products shows that PNGase F PRIME digestion led to more complete glycan release and also allowed for the cleavage of glycans not released by the commercially-available enzymes when used at the same concentrations with the same digestion conditions. This advancement benefits applications that seek to understand glycobiology in a natural milieu. Preliminary data indicates that PNGase F PRIME has a higher specificity towards complex (tri and tetra-antennary) sialylated structures compared to the commercially sourced enzyme. Additionally, the work presented in this Analytical Chemistry paper utilized PNGase F PRIME for all in situ tissue work as the commercially-available PNGase enzymes did not work on native tissue to allow glycan recognition.

Urea is the principal end product of nitrogen metabolism in most mammals, formed by the enzymatic reactions of the Kreb's cycle.
Urea is a mild agent usually used in the solubilization and denaturation of proteins. It is also useful for renaturing proteins from samples already denatured with 6 M guanidine hydrochloride such as inclusion bodies; and in the extraction of the mitochondrial complex. It is commonly used to solubilize and denature proteins for denaturing isoelectric focusing and two-dimensional electrophoresis and in acetic acid-urea PAGE gels. Urea is used in cell or tissue culture media to increase the osmolality. Urea has also been used as fertilizer because of the easy availability of nitrogen; in animal feeds; it is reacted with aldehydes to make resins and plastics; condensed with malonic ester to form barbituric acid; used in the paper industry to soften cellulose; used as a diuretic; enhances the action of sulfonamides; an antiseptic.
Urea in solution is in equilibrium with ammonium cyanate. The form that reacts with protein amino groups is isocyanic acid. Urea in the presence of heat and protein leads to carbamylation of the proteins. Carbamylation by isocyanic acid interferes with protein characterization because isocyanic acid reacts with the amino terminus of proteins, preventing N-terminal sequencing. Isocyanic acid also reacts with side chains of lysine and arginine residues resulting in a protein that is unsuitable for many enzymatic digests. In addition, carbamylation often leads to confusing results from peptides having unexpected retention times and masses. When performing enzymatic protein digests it is important to remove urea first. Even though some enzymes will tolerate small amounts of urea, the elevated temperature used for most reactions will lead to carbamylation during the course of the digest. The urea can be removed prior to digestion by fast reversed phase chromatography, spin columns, or dialysis.
Dissolve urea in deionized water to the desired concentration.For every 10 ml of solution, add 1 g of Amberlite® IRA-910.Stir for one hour at room temperature
