What CREBtide 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

CREBtide sits within the Enzyme Substrates research class (CPC reference SUBS-013). 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 CREBtide 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).

Frequently asked questions

What is CREBtide?

CREBtide (CPC catalog code SUBS-013) 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 CREBtide studied for?

Published and internal research programs use CREBtide 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 CREBtide FDA-approved for human use?

No. CREBtide 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 CREBtide typically used in the lab?

In a enzyme substrates workflow, CREBtide 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 CREBtide 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 CREBtide product page point to?

This kindr reference page mirrors CPC Scientific's catalog metadata for SUBS-013. 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 CREBtide?

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.
