Lateral-flow nitrocellulose membranes

A new specialised membrane for one-step separation of plasma from whole blood, without the use of centrifugation, has been introduced by Pall Life Sciences. The Pall Vivid plasma separation membrane is specifically engineered for the generation of plasma from whole blood.

The membrane’s properties permit the cellular components of blood to be captured in the larger pores without lysis. The plasma flows into the smaller pores on the downstream side of the membrane, and can be drawn out of the membrane by capillary action. Rapid separation yields plasma similar in high-performance liquid chromatography (HPLC) profile to traditional centrifuged plasma.

The Pall Vivid plasma separation membrane is available in three grades. Fast separation occurs in less than two minutes and the membrane shows low haemolysis and low non-specific binding of diagnostic biomarkers such as troponin I.
