PolyPeptide Labs is a world leader in the manufacture of polypeptide, custom peptide Synthesis, peptide synthesis and generic peptide : generic GMP peptide and non-GMP peptide. PolyPeptide provides global support for a quality solution.
A linear chain of amino acid residues is called a polypeptide. Fig. 3 shows the structures of α-amino acid, the formation of the peptide bond in polypeptide chain and the three-dimensional representation of protein structure. Proteins differ from one another primarily in their sequence of α-...

Nanopores are single-molecule sensors used in nucleic acid analysis, whereas their applicability towards full protein identification has yet to be demonstrated. Here, we show that an engineered Fragaceatoxin C nanopore is capable of identifying individua
1、短鏈peptides的定義含有數個至數十個胺基酸者,稱為peptide 或polypeptide;百個以上者可稱蛋白質,至於其間的模糊地帶,稱蛋白質或多汰均可。另一方面,很多胺基酸也有生理作用,例如味素的成分是麩胺酸,也是神經傳導物質的一種;而色胺酸有安眠的作用,牛奶中含有很多色胺酸(9)。有許多peptides已經具有生理功能,...
This is exemplified by the discovery of glucagon-like peptide (GLP)-1 and pancreatic polypeptide hormone (PYY). GLP-1 is a peptide hormone of 30 amino acids, that originates from the proglucagon precursor protein and synthesized in the L cells of the small intestine. GLP-1 regulates both ...
The interaction between the polypeptide molecule and the protein is enhanced, and the peptide can pass through the cell membrane and is not easily hydrolyzed, and has higher pharmacological activity than the previous small molecule drugs and protein drugs. The synthesis of a peptide is different ...
2. Fusion DNA comprising (1) thioredoxin-like DNA, said thioredoxin-like DNA characterized by encoding a polypeptide that (a) has a three-dimensional structure substantially similar to that of E. coli thioredoxin and (b) contains an active site loop functionally and structurally equivalent to the...
