General description

Cholera filtrate promotes the activation of adenylate cyclase. It does not affect the activity of cyclic adenosine monophosphate (cAMP) phosphodiesterase.

Application

Cholerafiltrate has been used as a receptor destroying enzyme (RDE): inhemagglutination inhibition assay of serum samples, in microneutralizationassay of mice serum samples, in hemagglutination inhibition assay to removenon-specific inhibitors from the cell culture supernatant samples

Biochem/physiol Actions

Cholera filtrate is a bacterial sialidase receptor-destroying enzyme (RDE) and may be used as crude neuraminidase. It may also be used in serological testing for influenza.

Reconstitution

After reconstituting with 5ml sterile water, it will contain 0.01% MIT as preservative.

Other Notes

See a separate listing of neuraminidase for preparations showing higher activity.
For research use only. Not for use in diagnostic procedures.
