CKS-17 is a synthetic retroviral envelope peptide. CKS-17 has the highly conserved amino acid sequences occurring within the transmembrane envelope protein of many animal and human retroviruses. CKS-17 acts as an immunomodulatory epitope and exhibits suppressive properties for numerous immune functions.

Gastrin I (human) (sulfated) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Lignin is the main component of plant cell walls and is a renewable aromatic polymer. Lignin has strongly antioxidant activity.Lignin (Lignine) is a natural complex biopolymer with biodegradable and biocompatible.
