Peptides and proteins

Enzymes, peptides, and proteins are essential biomolecules used across molecular biology, biochemistry, diagnostics, cell culture, and advanced biotechnology. This category includes restriction enzymes, high-fidelity polymerases, ligases, reverse transcriptases, as well as synthetic peptides and purified recombinant proteins for functional assays, enzymatic studies, immunoassays (ELISA, Western Blot), and structure–function analysis. Designed to deliver high purity, stable enzymatic activity, and experimental reproducibility, these reagents support critical workflows such as PCR/qPCR, cloning, gene expression, cell signaling, and proteomics.
