Supplier: VWR Chemicals

A protease-free grade albumin for RIA and ELISA applications, produced by a heat-shock process in caprylic acid.

Supplier: ENZO LIFE SCIENCES

Cell permeable peptide that blocks eNOS (NOS III) activity and cellular nitric oxide (NO) release in vitro and reduces inflammation and tumorigenesis in vivo. Caveolin-1 interacts with several lipid-modified signalling ligands, such as EGFR, eNOS, G-protein α-subunits, PKCα, H-Ras, and Src, via the C1-SD82-101 sequence.

Supplier: VWR Chemicals

A standard grade albumin for basic applications, produced by a heat shock process in caprylic acid.

Supplier: VWR Chemicals

A Cohn fraction V albumin produced by cold ethanol fractionation with minimum use of chemicals. Fatty acids and native sialic acid residues are preserved in this BSA.

Supplier: VWR Chemicals

Biological buffers are useful for cell culture in vitro, enzyme assays and some electrophoretic applications at physiological pH.

Supplier: VWR Chemicals

A higher purity product than standard grade or Cohn fraction V material. It is negative for globulins that interfere in many assays.

MG-132 is a potent, cell permeable and selective proteasome inhibitor (Ki = 4 nM).1 It inhibits NF-κB activation by preventing IκB degradation (IC50 = 3 μM). The peptide blocks degradation of short-lived proteins, which in turn induces HSP and ER chaperone expression, leading to thermotolerance (1 μM MG-132, 2 h.). It also stimulates neurite outgrowth in PC12 cells (20 nM optimal). The peptide has also been reported to increase the survival rate of mesenchymal stem cells following their transplantation. IC50’s for inhibition of Suc-LLVY-AMC and Z-LLL-AMC cleaving activities of proteasome were 0,85 and 0,1 μM respectively. The ubiquitin-proteasome system (UPS) and autophagy serve as two complementary, reciprocally regulated protein degradation systems, thus blockade of UPS by MG-132 activates autophagy.

Transforming growth factors (TGFs) are multifunctional peptides that regulate growth and differentiation in most cell types. The TGF-β family of proteins signal through serine/threonine kinase receptors. TGF-β isoforms (TGF-β1, -β2, and –β3) have overlapping, yet distinct biological actions in developing and adult tissues. TGF-β3 is an important factor in regulating cell adhesion and accelerating wound repair. TGF-β3 also functions during osteoblast proliferation, chemotaxis, and collagen synthesis.

Recombinant Human Gastrin Releasing Peptide (from HEK293 cells)

Supplier: ProSci Inc.

Coagulation factor IX（F9), is a member of the peptidase S1 family. It contains two EGF-like domains, a Gla domain and a peptidase S1 domain. It is primarily expressed in the liver and secreted in plasma. Factor IX is a vitamin K-dependent plasma protein that participates in the intrinsic pathway of blood coagulation by converting factor X to its active form in the presence of Ca2+ ions, phospholipids, and factor VIIIa. Mutations in position 43 and 46 prevents cleavage of the propeptide, mutation in position 93 probably fails to bind to cell membranes, mutation in position 191 or in position 226 prevent cleavage of the activation peptide. Mutations of human F9 can result in thrombophilia and recessive X-linked hemophilia B (HEMB). An X-linked blood coagulation disorder characterized by a permanent tendency to hemorrhage, due to factor IX deficiency. It is phenotypically similar to hemophilia A, but patients present with fewer symptoms. Many patients are asymptomatic until the hemostatic system is stressed by surgery or trauma.
