Human albumin, fraction V, 10 g

This human protein is prepared by a modification of the Cohn procedure. Albumin may be used to eliminate background interference in ELISA's or other enzyme assay systems. It is also used in absorption, distribution, metabolism, and excretion (ADME) pharmacological research; cell culture; drug delivery research; and cryopreservation of cells. Human and bovine albumins contain 16% nitrogen and are often used as standards in protein calibration studies. Due to their free hydrophobic region fatty acid free albumins are used to solubilize lipids in tissue culture, and are also used as blocking agents in Western blots or ELISA applications. Globulin free albumins are suitable for use in applications where no other proteins should be present (e.g., electrophoresis). Serum albumin functions as a carrier protein for steroids, fatty acids, and thyroid hormones, and is vital in regulating the colloidal osmotic pressures of blood. Albumin is also seen to bind to exogenous substances, particularly drugs (e.g., ibuprofen, warfarin), and strongly influence their pharmacokinetics. Oxidative stress leading to changes in the redox state of albumin has widely varied effects on its physiological function.

Purified human transferrin, 10 mg

Product is the lyophilized powder of human transferrin and buffer salts. ransferrin is a glycoprotein with homologous N-terminal and C-terminal iron-binding domains. The N-terminal and C-terminal domains of this protein are globular moieties of about 330 amino acids. Each of these domains is divided into two sub-domains, with the iron- and anion-binding sites found within the intersubdomain cleft. The binding cleft opens with iron release and closes with iron binding. Transferrin binds iron with an association constant of approximately 1022 M-1. Ferric iron couples to transferrin only in the presence of an anion (usually carbonate) that serves as a bridging ligand between metal and protein, excluding water from the two coordination sites. Without the anion cofactor, iron binding to transferrin is negligible. In the presence of anions, ferric transferrin is resistant to all but the most potent chelators. The remaining four coordination sites are provided by the transferrin protein - a histidine nitrogen, an aspartic acid carboxylate oxygen, and two tyrosine phenolate oxygens. Available evidence suggests that anion-binding takes place prior to iron-binding. Iron release from transferrin involves protonation of the carbonate anion, loosening the metal-protein bond.

Lactoferrin

Lactoferrin is an iron binding protein. It is structurally similar to transferrin, the plasma iron transport protein; but lactoferrin has a much higher affinity for iron (250 fold). It is very abundant in colostrum and small amounts can also be found in tears, saliva, mucous secretions and in the secondary granules of neutrophils. It is made by mucosal epithelium and neutrophils and is released by these cells in response to inflammatory stimuli. Bacterial growth is inhibited by its ability to sequester iron and also permeabilize bacterial cell walls by binding to lipopolysaccharides through its N-terminus. Lactoferrin can inhibit viral infection by binding tightly to the viral envelope protein. This prevents cell-virus fusion by blocking the binding domain. Lactoferrin appears to activate host defense systems in part by stimulating the release of interleukin-8, a neutrophil activator. It may also be involved in antibody and interleukin synthesis, lymphocyte proliferation and complement activation.

Beta 2-microglobulin is present in small amounts in serum, csf, and urine of normal people, and to a much greater degree in the urine and plasma of patients with tubular proteinaemia, renal failure, or kidney transplants. Human Beta 2 microglobulin levels can rise either because its rate of synthesis has increased (e.g. in AIDS, malignant monoclonal plasma cell dyscrasia, solid tumors and autoimmune disease) or because of impaired renal filtration (e.g. due to renal insufficiency, graft rejection or nephrotoxicity induced by post-transplantation immunosuppressive therapy). Beta-2 microglobulin levels might also be elevated in multiple myeloma and lymphoma cases.

Recombinant human IGF-I

The IGFs are mitogenic polypeptide growth factors that stimulate the proliferation and survival of various cell types including muscle, bone, and cartilage tissue in vitro. IGFs are predominantly produced by the liver, although a variety of tissues produce the IGFs at distinctive times. The IGFs belong to the Insulin gene family, which also contains insulin and relaxin. The IGFs are similar by structure and function to insulin, but have a much higher growth-promoting activity than insulin. IGF-II expression is influenced by placenta lactogen, while IGF-I expression is regulated by growth hormone. Both IGF-I and IGF-II signal through the tyrosine kinase type I receptor (IGF-IR), but, IGF-II can also signal through the IGF-II/Mannose-6-phosphate receptor. Mature IGFs are generated by proteolytic processing of inactive precursor proteins, which contain N-terminal and C-terminal propeptide regions. Recombinant human IGF-I and IGF-II are globular proteins containing 70 and 67 amino acids, respectively, and 3 intra-molecular disulfide bonds.

Zymolyase 100T (100Ku/g)

Zymolyase-100T is an enzyme preparation from a submerged culture of Arthrobacter luteus which effectively lyses cell walls of viable yeast cells. This preparation is lyophilized enzyme partially purified by affinity chromatography and contains 100,000 units enzyme/g. The primary enzyme in this preparation responsible for lysis of viable yeast cells in ß-1,3-glucan laminaripentaohydrolase. It hydrolyzes glucose polymers at the ß-1,3-glucan linkages releasing laminaripentaose as the principal product.

Pokeweed mitogen from Phytolacca americana

Pokeweed mitogen (PWM) is extracted from pokeweed roots. This protein has hemagglutinating, leukoagglutinating, and mitogenic properties. PWM is not blood group specific, but has affinity for N-acetyl-β-D-glucosamine oligomers.

Human albumin crystallized (1x Cohn crystallized)

ALBUMIN, HUMAN is recommended for use in absorption, distribution, metabolism, and excretion (ADME) pharmacological research; cell culture; drug delivery research; and cryopreservation of cells. Prepared using Cohn method IV. The material is non-reactive for HbsAg, Anti-HCV 3.0, Anti-HIV-1/2 and STS (RPR). This material is also negative for HIV-1 and HCV by PCR. Product Description Albumins are a group of simple proteins found in the body fluids and tissues of animals, and in some plant seeds. It is a single polypeptide chain with one free sulfhydryl group (Cys34) and 17 intrachain disulfide bonds. Biochem/physiol Actions Albumins are soluble monomeric proteins found in the body fluids and tissues of animals and in some plant seeds. Serum albumin functions as a carrier protein for steroids, fatty acids, and thyroid hormones. Serum albumins are also vital in regulating the colloidal osmotic pressures of blood.
