What Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt is studied for

  • Kinetic (kcat / Km) characterization of proteases and hydrolases
  • High-throughput inhibitor screening
  • Selectivity profiling across related enzyme families
  • Diagnostic and academic activity assays

Mechanism of action

Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt sits within the Enzyme Substrates research class (CPC reference SUBS-041). The peptide encodes a recognition sequence flanked by a reporter group (pNA, AMC, MCA, FAM/DABCYL). Enzyme cleavage releases the reporter, producing a quantifiable optical signal proportional to catalytic activity. Investigators typically incorporate Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt as a reference standard, tool ligand, or substrate in the assay contexts listed above. Read on kinetic plate readers with the reporter-appropriate filter set (e.g. 405 nm, 380/460 nm).

Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt (CPC catalog code SUBS-041) is a synthetic enzyme substrate (research reagent) in the enzyme substrates category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

What is Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt studied for?

Published and internal research programs use Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt as a reference standard in enzyme substrates workflows — for example, kinetic (kcat / km) characterization of proteases and hydrolases and high-throughput inhibitor screening. Human clinical evidence is not established.

Is Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt FDA-approved for human use?

No. Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt is a research-grade reference peptide and is not approved by the FDA or any national regulator for human or veterinary therapeutic use. It is offered exclusively for in-vitro laboratory research and does not ship to the United States for consumer use.

How is Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt typically used in the lab?

In a enzyme substrates workflow, Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Read on kinetic plate readers with the reporter-appropriate filter set (e.g. 405 nm, 380/460 nm).

How should Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt be stored?

Store lyophilized at −20 °C, protected from light. DMSO stocks stable at −80 °C for months. Follow your institution's standard operating procedures for handling synthetic peptides.

Where does the Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt product page point to?

This kindr reference page mirrors CPC Scientific's catalog metadata for SUBS-041. The upstream reference sheet — including sequence, purity, MW, and application notes where published — is linked from the buy panel. All orders placed on kindr Peptides ship internationally under research-use terms only.

What quality specifications apply to Ac-PLG-((S)-2-mercapto-4-methyl-pentanoyl)-LG-OEt?

Research-grade peptides in the CPC catalog are synthesized by solid-phase peptide synthesis (SPPS), purified by preparative RP-HPLC, and characterized by analytical HPLC and mass spectrometry. Typical purity is ≥95%; certificate of analysis is available on request.
