Description:
Glutaraldehyde is a bifunctional protein cross-linking reagent, reacting with NH2 groups to form Schiff's bases.
Sporicidal agent. Glutaraldehyde reacts through cross-linking to impart water resistance to protein and polyhydroxy compounds. It is also a reducing agent for photochemicals. In organic syntheses, the reactive carbonyl groups of glutaraldehyde suggest its use as an intermediate for the production of resins, dyestuffs, and pharmaceuticals. Glutaraldehyde is a disinfectant, which is rapidly effective against vegetative forms of Gram-positive and Gram-negative bacteria. It is also effective against acid-fast bacteria, bacterial spores, some fungi and viruses, including hepatitis B virus and human immunodeficiency virus. It can also be used for stabilization of proteins on agarose beads, activation of polystyrene and glass for immobilization of antibodies and antigens, and coupling peptides onto carrier proteins. Can be used for preparing emulsions for making photographic film. Also for use as an electron microscopy fixative or cell fixation. Store at +4 °C. Store Under Nitrogen

Description:
MES is a zwitterionic buffer. One of the "Good" buffers developed for biological applications. It has the advantages of maximum water solubility and minimum solubility in all other solvents, minimal salt effects, minimal change in pK with temperature, chemically and enzymatically stable, minimal absorption in visible or UV spectral range.
A buffer using MES free acid can be prepared by titrating the free acid with sodium hydroxide to the desired pH (pKa ± 1). Alternatively, volumes of equimolar MES free acid and sodium or potassium MES can be mixed to attain the desired pH.

Description:
Sodium azide used as a preservative for laboratory reagents; a bacteriostatic agent in storage solutions. Inhibits gram negative flora so is therefore included in culture media for the selective isolation of Streptococci and Staphylococci. It has been used to avoid bacterial contamination during RPC-5 column chromatography of DNA fragments.
Catalyst for: • Oxidative decarboxylation • Michael addition reactions Reagent for synthesis of • Blue fluorescent copolymers • Metal phosphonates • Arenes via aminations Involved in regioselective synthesis of prianosin B It is also a useful probe reagent, mutagen, and preservative. In hospitals and laboratories, it is a biocide (A biocide is a chemical substance or microorganism which can deter, render harmless, or exert a controlling effect on any harmful organism by chemical or biological means.) Sodium Azide is an inhibitor of peroxidase, myeloperoxidase, superoxide dismutase, galactose oxidase, catalase, haemoprotein enzymes and O2 evolution in photosynthesis. The mechanism of its inhibition and toxicity may be due to metal ion complexation and displacement from enzyme.

Description:
Alcohol dehydrogenases are a group of dehydrogenase enzymes that occur in many organisms. It is a metalloenzyme containing four tightly bound zinc atoms per molecule. Each subunit also contains a second zinc atom (conformational zinc), which stabilizes the enzyme’s tertiary structure. Per subunit, there are two distinct active site sulfhydryl groups which can be distinguished on the basis of differential reactivity with iodoacetate and butyl isocyanate. A histidine residue is considered to have an essential role.

Description:
Guanidine Hydrochloride is a protein denaturant and thus having an important role in molecular weight determinations.
Guanidine Hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of proteins. This strong denaturant can solubilize insoluble or denatured proteins such as inclusion bodies. This can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Guanidine HCl is used in the isolation of RNA to dissociate the nucleoprotein into its nucleic acid and protein moieties. It is an inhibitor of RNase. Highly concentrated (6 - 8 M) Guanidine HCl solutions are used to denature native globular proteins. It apparently disrupts hydrogen bonds which hold the protein in its unique structure. However, there also is evidence suggesting that guanidine hydrocholoride may disrupt hydrophobic interactions by promoting the solubility of hydrophobic residues in aqueous solutions.

Background Information
Fibrinogen is a blood protein that is involved in clotting and is converted to fibrin by thrombin. Fibrinogen has an approximate molecular weight of 340 kDa. It consists of three non-identical pairs of disulfidebonded chains. The α-chain has an approximate molecular weight of 63.5 kDa, the β-chain 56 kDa, and the γ-chain 47 kDa. At the amino termini, the three chains are connected in a dimeric disulfide knot (DSK). A second DSK occurs later in the molecule. Fibrinogen has approximately 4% carbohydrate content.
