Proteins and Peptides

Proteins are used in routine laboratory procedures such as binding enzymes or coupling peptides to carrier proteins. These kits, mixture solutions, and collagen matrices fulfill a myriad of essential laboratory functions for developing relationships between proteins and other cellular components. The stimulating proteins offered have various amino acid arrangements and functions to fulfill any sample manipulation for testing purposes in any field.

Catalog Number: (89151-948)

Supplier:  Enzo Life Sciences
Description:   Produced in HEK 293 cells. The extracellular domain of mouse TWEAK (aa 94-249) is fused at the N-terminus to tenascin-C (TNC) (chicken) (aa 110-139) and a FLAG®-tag.
Catalog Number: (89146-914)

Supplier:  Enzo Life Sciences
Description:   Cathepsin substrate
Supplier:  Rockland Immunochemical
Description:   Growth and Differentiation Factor 15 (GDF-15) is a TGFβ family member, made by the placenta and heart tissues, that has a role in regulating inflammatory and apoptotic pathways. GDF-15 has become an immerging marker of early heart disease and has the potential as being used as a molecule for screening patients for early heart failure. Recombinant human GDF-15 D is a non-glycosylated, disulfide linked homodimer, containing two identical 113 amino acid chains, with a total molecular weight of 24.5 kDa. There is a His to an Asp substitution at position 7.
Catalog Number: (89165-164)

Supplier:  Enzo Life Sciences
Description:   SUMO1-AMCA is a synthetic AMCA-peptide substrate based on the C-terminal residues of SUMO1 and is a useful fluorogenic substrate for deSUMOylating enzymes, including SENP1 (BML-UW9760). It has particular utility for the study of deSUMOylating activity where continuous monitoring of activity is essential. It provides an alternative substrate to SUMO1-AMC.

Description:   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.

Supplier:  Rockland Immunochemical
Description:   BAX is a proapoptotic protein of the BCL2 protein family. BAX forms a heterodimer with BCL2 and functions as an apoptotic activator. BAX interacts with and increases the opening of the mitochondrial voltage-dependent anion channel (VDAC), which leads to the loss in the mitochondrial membrane potential and the release of cytochrome c (1). The expression of BAX gene is regulated by the tumor suppressor p53 and BAX has been shown to be involved in p53-mediated apoptosis. Multiple alternatively spliced transcript variants, which encode different isoforms, have been reported for this gene (2). BAX Protein is ideal for investigators involved in Signaling Proteins, Apoptosis Proteins, AKT/PKB Pathway, Apoptosis/Autophagy, Cancer, Cardiovascular Disease, and Neurobiology research.

Description:   Negative control for Fc chimeric proteins
Supplier:  Rockland Immunochemical
Description:   FOS is a member of the FOS gene family that consists of 4 members: FOS, FOSB, FOSL1, and FOSL2. FOS gene encodes a leucine zipper protein that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation (1). In some cases, expression of the FOS gene has also been associated with apoptotic cell death. FOS overexpression leads to decreased phosphorylation and dimerization of STAT1, which in turn downregulates p21 gene expression (2). This regulatory pathway may enhance the proliferation of lymphocytes in rheumatoid arthritis patients. FOS Protein is ideal for investigators involved in Signaling Proteins, Transcription Proteins, Angiogenesis, Apoptosis/Autophagy, Cancer, Cardiovascular Disease, ERK/MAPK Pathway, Invasion/Metastasis, and Neurobiology research.
