Du sökte efter: Proteins and Peptides
Proteins are used in routine laboratory procedures such as binding enzymes or coupling peptides to carrier proteins. These kits, mixture solutions, and collagen matrices fulfill a myriad of essential laboratory functions for developing relationships between proteins and other cellular components. The stimulating proteins offered have various amino acid arrangements and functions to fulfill any sample manipulation for testing purposes in any field.

Poly-L-lysine hydrobromide
Supplier: SIGMA ALDRICH MICROSCOPY
Poly-L-lysine is a positively charged amino acid polymer with approximately one HBr per lysine residue. The hydrobromide allows the poly-L-lysine to be in a crystalline form soluble in water. A small amount of product may be found in the beta structure because the HBr interferes with hydrogen bonding between amino and either the carboxyl groups or N or O containing moieties.

Human amyloid-beta (1-40) peptide
Supplier: Cayman Chemical
Amyloid-β (1-40) peptide Aβ (1-40) is a 40-residue protein fragment of the C-terminal portion of the β-amyloid protein implicated in Alzheimer’s disease. Aβ (1-40) is more abundant, less neurotoxic, and does not form oligomers as easily as amyloid-β (1-42) peptide (Aβ (1-42).
