Immunofiltration

Definition

Immunofiltration is a laboratory technique that combines filtration and immunoassay principles to detect specific antigens or antibodies in a sample. It involves passing a liquid sample through a membrane, which captures the target molecule using an antigen-antibody reaction.

5 Must Know Facts For Your Next Test

1. Immunofiltration often uses microporous membranes to capture antigens or antibodies.
2. The technique can rapidly detect pathogens or immune responses in clinical samples.
3. It is commonly used for point-of-care testing due to its simplicity and speed.
4. Immunofiltration can be used in conjunction with Enzyme Immunoassays (EIAs) for enhanced sensitivity.
5. Applications include diagnosing infectious diseases, monitoring immune responses, and verifying vaccine efficacy.
