Substance P / HRP Bispecific Monoclonal Antibody (P4C1) – Thimerosal-free

Lyophilized antibodies can be kept at 4ºC for up to 3 months and should be kept at -20ºC for long-term storage (2 years). To avoid freeze-thaw cycles, reconstituted antibodies should be aliquoted before freezing for long-term (1 year) storage (-80ºC) or kept at 4ºC for short-term usage (2 months). For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made with the assay buffer. After the maximum long-term storage period (2 years lyophilized or 1 year reconstituted) antibodies should be tested in your assay with a standard sample to verify if you have noticed any decrease in their efficacy. To limit antibody loss or degradation, BSA (final concentration 1%) and sodium azide (final concentration 0.02%) can be added to the suggested first dilution. It is important to first verify if those preservatives are compatible with your assay.

This is a bispecific antibody which recognizes (A) Substance P and (B) Horseradish peroxidase types I, II, VI, IX, X. This antibody recognizes the COOH-terminal end of substance P. It does not recognize Leu- or Met enkephalin, somatostatin or beta-endorphin; cross-reactivity with eledoisin: 5%. It recognizes Substance P in post-mortem tissue of the human brain.
