Reta

Description

What it is

Reta is a synthetic, multiply-modified acylated research peptide supplied as a lyophilised powder for laboratory use. Its chemistry features non-coded amino-acid substitutions that improve resistance to enzymatic breakdown, an amidated C-terminus, and a long-chain fatty-diacid modification that promotes reversible binding to serum albumin. Typically supplied as the acetate salt. This listing describes a chemical reagent only, and makes no reference to any medicine, indication or physiological effect.

Research context

Reta is stocked as a reference-grade peptide for in-vitro characterisation and analytical method development by qualified laboratory professionals. Because it is a long, heavily modified peptide with no pharmacopoeial reference standard, its identity rests on the supplier’s analytical package rather than on any monograph.

Handling and storage

Supplied lyophilised in a sealed vial. For laboratory handling the powder is reconstituted with bacteriostatic or sterile water; this is a handling note, not a dose or a use instruction. Store the lyophilised powder cold and protected from light, avoid repeated freeze-thaw, and treat any reconstituted material as cold-chain dependent and short-lived.

Testing and quality

Every batch is third-party tested. The certificate of analysis states the salt form, reports HPLC purity with chromatogram and confirms identity by mass spectrometry, expected versus observed mass. Supplied for laboratory research use only. Not for human or animal consumption.
