B-720-25 25 mg $ 119.00
B-720-100 100 mg $ 199.00

Description

Biotin‐PEG4‐NHS Ester is a pegylated, highly hydrophilic biotinylation reagent for simple and efficient biotin labeling of antibodies, proteins and other primary amine-containing biomolecules.

Biotin‐PEG4‐NHS Ester reacts specifically and efficiently with primary amines (e.g., side chain of lysine residues or aminosilane-coated surfaces) at pH 7-9 to form covalent bonds. The hydrophilic polyethylene glycol (PEG) spacer arm of this reagent imparts water solubility that is transferred to the labeled molecule, thus reducing aggregation of labeled proteins stored in solution. The PEG spacer arm also gives the reagent a long and flexible connection to minimize steric hindrance involved with binding to avidin molecules.

Description

Hepatitis B virus (HBV) is an infectious, and potentially fatal, human disease that causes serious liver disease. There are three start codons on the Gene S HBV surface protein antigen (HBsAg) that divide the gene into three sections: pre-S1, pre-S2, and S. These start sites create three carboxyl, coterminal polypeptides that are called large (LHB, the order from surface to the inside: pre-S1, pre-S2, and S), middle (MHB, containing the pre-S2 and S portion) and small (SHB, covering only the S portion). The pre-S1 amino acid region of LHBs consists of 119 amino acids and has been shown to interact with its human binding partner, γ2-adaptin, to subvert the membrane-trafficking apparatus to mediate virion export. HBsAg-PreS1 can be used for Immunochromatography, monoclonal and polyclonal antibody preparation or for ELISA analysis.

IL1B (IL-1 beta), Porcine

Catalog ID Size Pricing
1810-01B-10 10 μg $ 165.00

Description

Interleukin-1 beta (IL1B) is a nonsecreted pro-inflammatory cytokine produced mainly by activated macrophages, as well as neutrophils, epithelial cells and endothelial cells. It possesses metabolic, physiological and hematopoietic activities, and plays one of the central roles in the regulation of immune responses. Both IL1A and IL1B bind to the same receptor and have similar biological properties. Recombinant porcine IL1B shares 63-70% amino acid sequence identity with canine, cotton rat, equine, feline, human, mouse, rat and rhesus IL1B.

Catalog ID Size Pricing
1810-01C-5 5 μg $ 115.00

Description

IL1RN, initially called the IL1 inhibitor, is encoded by the IL1RN gene and is a member of the interleukin 1 cytokine family. IL1RN is secreted by various types of cells including immune cells, epithelial cells, and adipocytes. ILRN functions to inhibit the activity of IL1 by binding to receptor IL1R1, preventing its association with the co-receptor IL1RAP for signaling. IL1RN is also used in the treatment of rheumatoid arthritis, an autoimmune disease in which IL1 plays a key role. The porcine IL1RN is a single non-glycosylated polypeptide chain that has been shown to block the inflammatory responses induced by IL1 both in vitro and in vivo.

IL2, Porcine

Catalog ID Size Pricing
1810-02-10 10 μg $ 165.00

Description

IL2 is a powerful immunoregulatory lymphokine produced by T-cells in response to antigenic or mitogenic stimulation. It is expressed by CD4+ and CD8+ T-cells, γδ T-cells, B-cells, dendritic cells, and eosinophils. The receptor for IL2 (IL2R) consists of three subunits (55 kDa IL2RI, 75 kDa IL2RJ, 64 kDa common gamma chain Gc/IL2RG) that are present on the cell surface in varying preformed complexes. IL2/IL2R signaling is required for T-cell proliferation and other fundamental functions which are essential for an immune response. Recombinant porcine IL2 shares about 72% amino acid sequence identity with mouse, human and rat IL2. It also shares 60% and 67% acid sequence identity with rhesus macaque and Equus caballus IL2, respectively.

Description

Interleukin-8 (IL8) is encoded by the IL8 gene and produced by macrophages and other cell types such as epithelial cells. IL8 is also synthesized by endothelial cells, and then stored in vesicles. There are many receptors capable of binding to IL8; however, the receptors that have the greatest affinity are CXCR1 and CXCR2. As a member of the CXC chemokine family, IL8 is a player in the induction of chemotaxis in its target cells, like neutrophil granulocytes, basophils and T-cells. IL8 is often associated with inflammation and has been cited as a pro-inflammatory mediator in gingivitis and psoriasis.
