Cecropin B

Cecropin B (CPC catalog code ATMP-003) is a synthetic antimicrobial peptide (amp) reference standard in the antimicrobial category. It is provided as a lyophilized ~1 mg vial for in-vitro research use only.

Published and internal research programs use Cecropin B as a reference standard in antimicrobial workflows — for example, minimum inhibitory concentration (mic) screens against gram-positive and gram-negative panels and biofilm disruption and anti-biofilm surface coatings. Human clinical evidence is not established.

No. Cecropin B 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 antimicrobial workflow, Cecropin B is reconstituted in sterile buffer or DMSO (solubility-dependent) and applied in the researcher's chosen assay format. Most commonly used in broth microdilution MIC assays (CLSI M07), radial diffusion assays, and membrane-permeabilization (SYTOX / DiSC₃-5) readouts.

Lyophilized peptide is stable long-term at −20 °C. Reconstituted stock solutions are typically stored at 4 °C for short-term use or aliquoted and frozen for longer storage. Follow your institution's standard operating procedures for handling synthetic peptides.

This kindr reference page mirrors CPC Scientific's catalog metadata for ATMP-003. 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.
