Storage: Room Temperature
Guanidine hydrochloride consists of a network of guanidinium cations and chloride anions linked by N–H•••Cl hydrogen bonds, it is a strong chaotropic agent. Guanidine HCl may agglomerate upon storage. It may appear as a free-flowing crystalline powder, a free flowing powder with solid material dispersed throughout, or a solid. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine HCl appear identical.
Guanidine hydrochloride can be used as the first step in refolding proteins or enzymes into their active form. Urea and dithiothreitol (DTT) may also be necessary. Also used in the isolation of RNA. Guanidine hydrochloride is a strong chaotropic agent useful for the denaturation and subsequent refolding of protein, it can solubilize insoluble or denatured proteins such as inclusion bodies and be used for the recovery of periplasmic proteins.

Butyric acid is used in the preparation of various butyrate esters. Low-molecular-weight esters of butyric acid, such as methyl butyrate, have mostly pleasant aromas or tastes. As a consequence, they find use as food and perfume additives. It is also used as an animal feed supplement, due to the ability to reduce pathogenic bacterial colonization.

Product is the lyophilized powder of fluorescein-5-isothiocyanate (FITC "Isomer I")-conjugated goat IgG fraction to mouse complement C3 and buffer salts.

Supplier: MP Biomedicals

This product is fluorescein-5-isothiocyanate (FITC "Isomer I")-conjugated goat affinity purified F(ab')2 fragments to mouse immunoglobulins (IgG,IgA,IgM) and buffer salts.The total protein is measured by absorbance (A)280 nm); F/P ratio is calculated using absorbance at 491.5nm. Antibody titer of the affinity purified F(ab')2fragments is standardized with an in-house control by immunoelectrophoresis. The affinity purified F(ab')2 fragment is tested for purity at 10 mg/mL using immunoelectrophoresis. The product is goat F(ab')2; no trace of albumin, whole molecule IgG or Fc is detected. This product contains sodium azide. To prevent formation of toxic vapors, do not mix with strongly acidic solutions. To prevent formation of potentially explosive metallic azides in metal plumbing, always wash into drain with copious quantities of water.

The total protein is measured using the Biuret procedure with bovine albumin as the standard; F/P ratio is calculated using absorbance at 491.5nm. Antibody titer of the IgG fraction is standardized with an in-house control by immunoelectrophoresis; No trace of albumin is detected. Antibody activity to non-immunoglobulin serum proteins is not present.

Fetuin bovine is a protein with the ability to bind to the insulin receptor and inhibit insulin action. Fetuin has been used in studies of type 2 diabetes mellitus (T2DM). In patients with T2DM, fetuin has been shown to be significantly lower when compared to control patients. Fetuin has also been used in studies to demonstrate its protective role in the development of arterial calcification. Fetuin also contributes to the attachment and spreading of cells in culture medium.

Fetuin is a protein containing 12 Cys residues, all involved in disulphide bridges. The composition of bovine fetuin (weight %) is polypeptide 74%, hexose 8,3%, hexosamines 5,5%, and sialic acid 8,7%.
