SRP3013 Beta D-4 human recombinant, expressed in E. coli, ≥98% (SDS-PAGE), ≥98% (HPLC), cell culture tested Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. Recombinant human BD-4 is a 6.0 kDa protein containing 50 amino acid residues.
SRP3011 Beta D-1 (36 aa) human recombinant, expressed in E. coli, ≥98% (SDS-PAGE), ≥98% (HPLC), cell culture tested Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. Recombinant human BD-1 is a 3.9 kDa protein containing 36 amino acid residues.
SRP3012 Beta D-1 (47 aa) human recombinant, expressed in E. coli, ≥98% (SDS-PAGE), ≥98% (HPLC), cell culture tested Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. Recombinant human BD-1 is a 5.0 kDa protein containing 47 amino acid residues.
C6830 Cecropin A ≥97% (HPLC), powder Antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.
C1796 Cecropin B ≥97% (HPLC), powder Antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.
C7927 Cecropin P1 Porcine ≥95% (HPLC), powder Antibacterial peptide originally identified in moths (Hyalophora cecropia) and later in pig intestine.
D2043 Defensin HNP-1 human ≥80% (HPLC) This is an endogenous antibiotic peptide and monocyte chemotactic peptide produced by human neutrophils. Defensins are a family of 3-4 kDa (29-34 amino acids) peptides found in the granules of mammalian phagocytes. The members of this family are variably arginine-rich and share six conserved cysteine residues that participate in intramolecular disulfide bonds.
D6790 Defensin HNP-2 human ≥95% (HPLC) This is an endogenous antibiotic peptide and monocyte chemotactic peptide produced by human neutrophils. Defensins are a family of 3-4 kDa (29-34 amino acids) peptides found in the granules of mammalian phagocytes. The members of this famuly are variably arginine-rich and all share 6 conserved cysteine residues that participate in intramolecular disulfide bonds.
M7152 Magainin I ≥97% (HPLC) Antibiotic peptide. Thought to preferentially bind to anionic phospholipids abundant in bacterial membranes with the formation of dynamic peptide-lipid supramolecular pore and cell permeabilization, magainins are positively charged and amphiphatic. Binding to artificial neutral membranes has also been demonstrated.
M7402 Magainin II ≥97% (HPLC) Antibiotic peptide. Magainins are positively charged and amphiphatic. Thought to preferentially bind to anionic phospholipids abundant in bacterial membranes with the formation of dynamic peptide-lipid supramolecular pore and cell permeabilization. Binding to artificial neutral membranes has also been demonstrated.
SRP3126 NP-1 human recombinant, expressed in E. coli, ≥98% (SDS-PAGE), ≥98% (HPLC), cell culture tested Neutrophil peptide-1 (NP-1) exhibits antimicrobial activity. It also has a chemotactic function in dendritic cells. It has a role in the growth and metastasis of cancer cells. The protein acts as multifunctional co-receptor and interacts with various signaling cascades. NP-1 associates with epithelial growth factor (EGF) and its receptor (EGFR). It also interacts with hepatocyte growth factor (HGF) and its receptor c-Met.
