Introduction to SS-31 (Elamipretide) SS-31, also known as Elamipretide or Bendavia, is a mitochondrial-targeted tetrapeptide with the sequence D-Arg-Dmt-Lys-Phe-NH2 (where Dmt is 2′,6′-dimethyltyrosine). This cell-permeable peptide has emerged as a significant research tool for studying mitochondrial function, oxidative stress, and bioenergetics in laboratory settings. SS-31 is unique among research peptides in its ability to selectively […]

What Are Peptide Blends? Peptide blends are research preparations containing two or more peptides combined in a single vial. These combinations are designed for researchers investigating potential synergistic or complementary mechanisms of action between different peptide compounds. By providing multiple peptides in one preparation, blends streamline research protocols and reduce the number of reconstitution steps […]

Why Purity Testing Matters In peptide research, compound purity directly impacts experimental validity. Impurities — whether truncated sequences, deletion peptides, residual solvents, or counterions — can introduce confounding variables that compromise research outcomes. Understanding the analytical methods used to verify peptide purity is essential for any researcher working with these compounds. High-Performance Liquid Chromatography (HPLC) […]

Why Proper Reconstitution Matters Reconstitution — the process of dissolving a lyophilized peptide into solution — is a critical step in any peptide research protocol. Improper reconstitution can damage peptide structure, reduce activity, introduce contamination, or cause aggregation. This guide covers essential reconstitution techniques for research peptides. What You Need Essential Supplies Lyophilized peptide vial […]

Why Proper Peptide Storage Matters Research peptides represent a significant investment, and their integrity directly impacts experimental reproducibility. Improper storage can lead to peptide degradation through hydrolysis, oxidation, aggregation, or deamidation — all of which compromise research outcomes. This guide covers best practices for handling and storing research peptides to maintain their purity and activity. […]
