FAQs
Quality is assured by adhering very strictly to specified, documented systems covering all aspects of membrane manufacture. Our quality management systems are ISO certified.
Superior consistency and stability. Due to optimized surface chemistry and unique processing method mdi membranes are highly consistent, point to point as well as roll to roll.
Pore size is only a name designation. One manufacturer’s pore size designation can be quite different from another’s. Bigger pore size is designated for membranes with faster wicking rates.
The wicking time is an important parameter for lateral flow membranes. mdi membranes of designated pore size will exhibit highly repeatable wicking time.
The problem is in the chemistry of the conjugate, conjugate release pad, and the sample pad. Adding buffers to maintain pH at 7.4 and adding blocking agents such as PVP will help.
False positive is primarily due to nonspecific binding of the conjugate particles. Using bigger pore size membrane can help reduce this, usually at the cost of sensitivity. Addition of detergents in the sample pad can also help minimize it.
The binding of the protein to the NC membrane grows stronger as it is dehydrated more and more. Usually, at room temp, (20-30° C), 50-60% RH the binding will reach a maximum in 3-5 days. For development, reasonable results can be expected with overnight drying at room temperature.
Membrane does not affect the stability of the assay. It is related to the chemistry of the assay, and many a times it improves by adding sucrose (0.5-1.0%) to the capture Antibody solutions.
The sample pad should not bind proteins nonspecifically, should exhibit good flow characteristics, and have adequate volume capacity. Its thickness should be such that it fits in the test device.
