Peptides are short strings of amino acids, the building blocks of proteins. While proteins are essential for human health, peptides have more specific functions and are more easily absorbed by the body. For instance, collagen peptides are used to boost skin health while creatine peptides have been shown to build muscle and improve athletic performance. Some peptides are also known to support anti-aging, anti-inflammatory and immune system function.

Peptide identification and quantification using MALDI-TOF mass spectrometry. Peptide fingerprinting and sequencing of single neurons reveals a complex pattern of neuropeptide prohormones in molluscan neurons. Identification of POMC processing products in single melanotrope cells by peptide-based omics. Spectral analysis of the C-terminal fragment of the small cardioactive peptide gene product by matrix-assisted laser desorption/ionization time of flight mass spectrometry.

Direct peptides are the highest quality Australian peptides, medication and supplements to support muscle development, weight loss, injury repair & recovery, sexual health, mood & sleep and more. These powerful and effective medical solutions help you reach your goals faster by targeting a variety of metabolic processes.

Copper peptide has been one of the most popular skincare ingredients lately. People are recommending it as a way to promote skin healing and rejuvenation. But research shows that copper peptide isn’t as good as people make it out to be, and it’s important to understand why before you start taking supplements that contain this ingredient.

The DPRA, also known as the Molecular Initiating Event (MIE) test method, measures the interaction of chemicals with epidermal proteins and quantifies the depletion of cysteine or lysine residues in model peptides. The Eurofins DPRA has been successfully validated by EURL ECVAM and is available as an alternative to animal testing.

DPRA is a robust test that aims to contribute to the evaluation of the skin sensitisation potential of chemicals by measuring the interaction with epidermal proteins and predicting the likelihood of a chemical inducing a skin sensitising response. It is performed on a tissue culture cell line and is fully automated. The data obtained from the DPRA correlates well with those of the other validated in vitro skin sensitisation tests and a cinnamic aldehyde.
