The Standard and Specialty series of multiwell chambers and the single well chambers use punched filters in a variety of sizes. They are available with standard untreated surface or with the wetting agent polyvinylpyrrolidone (PVP).

Polycarbonate track-etch (PCTE) membranes are the primary type of filters used in our chambers and instrument systems. This is a very thin membrane ranging between 6-10µm in nominal thickness. This membrane type offers excellent uniformity in pore size and density, as well as other benefits such as low extractables, low protein binding, and negligible absorption. These characteristics make it ideally suited for use in chemotaxis assays as well as other high purity screening assays.

PVP Treatment –PCTE membranes are available pre-treated with the wetting agent polyvinylpyrrolidone (PVP) which makes the surface hydrophilic. PVP-treated membranes are used when the media solutions cannot wet out the membrane by themselves. This occurs primarily when working with very small pore sizes or high viscosity media solutions. Certain cell types such as neutrophils do not adhere well to PVP treated membranes and tend to drop off after migrating. While this is problematic when quantifying filters on the membrane, some researchers using the ChemoTx® sytem or the MB-series 96-well chambers and quantifying in the plate find this to be an advantage. Extra-cellular matrix proteins do not adhere well to PVP treated membranes either. If your assay requires such coating, we recommend using PVP-free membranes.

Polycarbonate membranes are available in the following pore sizes and corresponding pore densities:

Pore size (+0/-20%) 2µm 3µm 5µm 8µm 10µm 12µm 14µm
Density (pores/mm2)
(tolerance +/- 15%)
2 x 104 2 x 104 4 x 103 1 x 103 1 x 103 1 x 103 5 x 102

 

Many factors other than cell type enter into the pore size selection process. Please see our page on Experiment Design.
