Animal-Free Recombinant Murine BD-3 (Legacy Tebubio ref. 167AF-250-41). Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The alpha-defensins are distinguished from the beta-defensins by the pairing of their three disulfide bonds. To date, six human beta-defensins have been identified; BD-1, BD-2, BD-3, BD-4, BD-5 and BD-6. beta-defensins are expressed on some leukocytes and at epithelial surfaces. In addition to their direct antimicrobial activities, they can act as chemoattractants towards immature dendritic cells and memory T cells. The beta-defensin proteins are expressed as the C-terminal portion of precursors, and are released by proteolytic cleavage of a signal sequence and, in some cases, a propeptide sequence. Beta-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. Recombinant Murine BD-3 is a 4.6 kDa protein containing 41 amino acid

Animal-Free Recombinant Human IFN-gamma (Legacy Tebubio ref. 167AF-300-02). IFN-gamma is an acid-labile interferon produced by CD4 and CD8 T lymphocytes as well as activated NK cells. IFN-gamma receptors are present in most immune cells, which respond to IFN-gamma signaling by increasing the surface expression of class I MHC proteins. This promotes the presentation of antigen to T-helper (CD4+) cells. IFN-gamma signaling in antigen-presenting cells, and antigen-recognizing B and T lymphocytes, regulates the antigen-specific phases of the immune response. Additionally, IFN-gamma stimulates a number of lymphoid cell functions, including the anti-microbial and anti-tumor responses of macrophages, NK cells, and neutrophils. Human IFN-gamma is species-specific and is biologically active only in human and primate cells. Recombinant Human IFN-gamma is a 16.8 kDa protein containing 144 amino acid residues.

Animal-Free Recombinant Human IFN-beta (Legacy Tebubio ref. 167AF-300-02B). Proteins of this family play an important role in inducing non-specific resistance against a broad range of viral infections. They also affect cell proliferation and modulate immune responses. Produced by peripheral blood leukocytes and lymphoblastoid cells, IFN-alpha is an acid-stable molecule that signals through IFN-alpha/betaR, which is also used by IFN-beta. Both IFNs have similar anti-viral activity and regulate expression of MHC class I antigens. IFN-alpha contains four highly conserved cysteine residues that form two disulfide bonds, one of which is necessary for biological activity. PeproTech's Recombinant Human IFN-beta is a 20.0 kDa protein containing 166 amino acid residues.

Animal-Free Recombinant Human IFN-lambda1 (Legacy Tebubio ref. 167AF-300-02L). IFN lambda1, 2, and 3 (also known as IL-29, IL-28A and IL-28B respectively) are distantly related to the IL-10 family and the interferons. All three IFN-lambdas use a distinct receptor system composed of an IFN-lambdaR1 subunit (also called CRF2-12) and IL-10R2 subunit (also called CRF2-14). Signaling through this receptor system induces antiviral defenses similar to, but distinct from, that of type I interferons. Recombinant Human IFN-lambda1 is a 19.8 kDa protein containing 178 amino acid residues.

Animal-Free Recombinant Human GM-CSF (Legacy Tebubio ref. 167AF-300-03). GM-CSF is a hematopoietic growth factor that stimulates the development of neutrophils and macrophages and promotes the proliferation and development of early erythroid megakaryocytic and eosinophilic progenitor cells. It is produced in endothelial cells, monocytes, fibroblasts and T-lymphocytes. GM-CSF inhibits neutrophil migration and enhances the functional activity of the mature end-cells. The human and murine molecules are species-specific and exhibit no cross-species reactivity. Recombinant Human GM-CSF is a 14.6 kDa globular protein consisting of 128 amino acids containing two intramolecular disulfide bonds and two potential N-linked glycosylation sites.
