Calpain Substrate

Calpain Substrate (CPC catalog code CASB-001) 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.

Published and internal research programs use Calpain Substrate 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.

No. Calpain Substrate 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.

In a enzyme substrates workflow, Calpain Substrate 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).

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.

This kindr reference page mirrors CPC Scientific's catalog metadata for CASB-001. 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.

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.
