Identification of short peptides as part of polypeptide complexes isolated from animal organs

Zhurkovich IK, Kovrov NG, Ryzhak GA, Mironova ES, Khavinson VKh · Uspekhi Sovremennoi Biologii (Biology Bulletin Reviews)

The paper the institute cites for the claim that its cartilage polypeptide complex consists of short peptides of 75–846 Da and contains the AED tripeptide — the only composition analysis of the extract that exists in the literature at all.

Population

Polypeptide complexes extracted from animal organs, including cartilage

Intervention

Mass spectrometry and HPLC to identify the short peptides present in each complex

Comparator

n/a

Limitations

Not indexed in PubMed; metadata confirmed against CrossRef only and the Russian-language full text was not retrievable, so the methods, batch count and quantitation behind the 75–846 Da figure could not be checked. Composition is not efficacy, and no independent laboratory has repeated the analysis.
