Critical Membrane Components Services

Nitrocellulose (NC) Membranes:
The NC membrane is the support medium that immobilizes the pre-coated antibody at the test region and the anti-IgG antibody at the control region. The size of the NC membrane component is customizable, but it is typically 20 mm wide and 260 mm long.

Colloidal Gold Conjugates:
Colloidal gold particles are 30 to 70 mm in size. They are conjugated to monoclonal antibodies at the Fc region via ionic interactions.

Sample Pads:
A sample pad consists of 3 layers of membrane. It aids in absorbency to allow the continuous lateral flow of the sample along the rapid test, and supplies the optimal reaction condition for the system.
