Proteiner
Proteiner används i rutinmässiga laboratorieprocedurer såsom att binda enzymer eller koppla peptider till bärarproteiner. Dessa kit, blandlösningar och kollagenmatriser fyller en mängd viktiga laboratoriefunktioner för att undersöka relationer mellan proteiner och andra cellulära komponenter. De stimulerande proteinerna som erbjuds har olika aminosyrasekvenser och funktioner och kan användas för provhantering inom alla forskningsområden.
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.
