Complement Factor P Functional Assay

Product Overview

The Factor P Functional assay is an enzyme-linked immunosorbent assay (ELISA) that combines principles of the functional complement activity assays with the use of labelled antibodies specific for deposited complement proteins. The amount of deposited complement proteins is proportional to the functional activity of Factor P in the sample.

The purpose of the product is to determine the function of Factor P in test samples. The functionality is determined qualitatively in relation to the calibrator (human serum) set to be 100% functional.

FOR RESEARCH USE ONLY. Not for use as a diagnostic tool or in the management of patients.

How it works

Principle of the functional factor P assay

Principle of the functional factor P assay

Factor P (FP) from the sample is bound by a capture antibody on the ELISA.

Principle of the functional factor P assay

Following a washing step, an FP-deleted reference serum is added. If the initial sample contains functional properdin, C3 from the reference will be cleaved to C3b, which binds to the bottom of the well.

An enzyme-conjugated detection antibody is used to detect C3b in the well.
