a chemical conjugate between a non-targeted peptide
and the catalytic A subunit of cholera toxin

This molecule is the perfect control for use with peptide CTA conjugates such as: SP-CTA and Neurotensin-CTA. The sequence of the non-targeted peptide of Blank-CTA is an 11-amino acid, randomly mixed version of the sequence of melanocyte-stimulating hormone, with amino acid residues that are typical of peptides that bind to G-protein-coupled receptors. Examination of the peptide sequence using NCBI/BLAST reveals no homologous sequences. In short, Blank-CTA is the perfect control molecule for behavioral experiments with our targeted CTA conjugates.

Effective Tool

• The perfect control molecule for peptide CTA conjugates
• There's no mixing of reagents; use it "as is" out of the vial
• No complicated calculations; use the same amount as the targeted toxin
• Ready to use: it comes sterile-filtered in phosphate-buffered saline
• It has the activity of non-targeted CTA, that is, almost none
