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.
Disclaimer
For research use only. Not for use in diagnostic procedures.
General description
Cholera filtrate promotes the activation of adenylate cyclase. It does not affect the activity of cyclic adenosine monophosphate (cAMP) phosphodiesterase.
Other Notes
See a separate listing of neuraminidase for preparations showing higher activity.
Preparation Note
After reconstituting with 5ml sterile water, it will contain 0.01% MIT as preservative.

An in vitro model using homogenates of the rat intestine and liver for studying the V. Cholerae culture filtrate effect on the adenylate cyclase system is proposed. Optimal conditions for the adenylate cyclase functioning have been investigated for this model.

Determining antigen specificity is vital for understanding B cell biology and for producing human monoclonal antibodies. We describe here a powerful method for identifying B cells that recognize membrane antigens expressed on cells. The technique depends on two characteristics of

A number of studies have suggested that influenza vaccination can provide protection against COVID-19, but the underlying mechanisms that could explain this association are still unclear. In this study, the effect of the 2021/2022 seasonal influenza vaccination on the immune

Blood cell counts often fail to report on immune processes occurring in remote tissues. Here, we use immune cell type-specific methylation patterns in circulating cell-free DNA (cfDNA) for studying human immune cell dynamics. We characterized cfDNA released from specific immune
