BMP-2 derived peptide, also known as bone morphogenetic protein 2 (BMP-2) derived peptide, corresponds to residues 73-92 of the knuckle epitope of BMP-2. BMP-2 derived peptide significantly inhibits the binding of recombinant human BMP-2 to both BMP receptors type IA and type II and also promotes the expression of osteocalcin mRNA and induces ectopic calcification in rat calf muscle. BMP-2 derived peptide may one of the receptor binding sites on BMP-2 and may stimulate bone precursor cells to induce calcification.

Normally, this peptide will be delivered in lyophilized form and should be stored in a freezer at or below -20 °C. For more details, please refer to the manual: Handling and Storage of Synthetic Peptides

Trifluoroacetic acid (TFA) has a significant impact on peptides due to its role in the peptide synthesis process.

TFA is essential for the protonation of peptides that lack basic amino acids such as Arginine (Arg), Histidine (His), and Lysine (Lys), or ones that have blocked N-termini. As a result, peptides often contain TFA salts in the final product.

TFA residues, when present in custom peptides, can cause unpredictable fluctuations in experimental data. At a nanomolar (nM) level, TFA can influence cell experiments, hindering cell growth at low concentrations (as low as 10 nM) and promoting it at higher doses (0.5–7.0 mM). It can also serve as an allosteric regulator on the GlyR of glycine receptors, thereby increasing receptor activity at lower glycine concentrations.

In an in vivo setting, TFA can trifluoroacetylate amino groups in proteins and phospholipids, inducing potentially unwanted antibody responses. Moreover, TFA can impact structure studies as it affects spectrum absorption.
