Anti-Head-Peptide can be used for ELISA and Immunocytochemistry.
The anti-head peptide serum was raised against the Periplaneta americana midgut neuropeptide, ANRSPSLRLRLRFamide, coupled to bovine thyroglobulin using glutaraldehyde.
Antisera to FMRFamide often only need the last two amino acids (RFamide) for recognition. In insects the FMRFamide-related peptides (FaRPs) are grouped into different families, which are expressed from different precursor genes: the FMRFamides), the myosuppressins, the sulfakinins and the head peptides. A crossreactivity of the anti-head peptide serum to the other FaRPs is visible, but the pattern of the head peptide immunoreactivity from brain, ventral nerve cord, midgut and antenna-heart (Fig 1, 2) is different to tested RF-amide sera (FMRFamide, anti-Perisulfakinin).
