8.0 μm pore polycarbonate membrane inserted transwell chambers

Manufactured by Corning
Sourced in United States

The 8.0-μm-pore polycarbonate-membrane-inserted transwell chambers are a type of laboratory equipment used for cell culture and membrane permeability studies. The chambers consist of a porous polycarbonate membrane inserted into a well, allowing for the separation of two compartments. This design facilitates the study of cell migration, invasion, and transport across the membrane.

Transwell Assay for Cell Migration

Cell migration ability was tested using 8.0-μm-pore polycarbonate-membrane-inserted transwell chambers (Corning, New York, NY, United States). The polycarbonate membrane of the upper chamber was coated with 0.1% gelatin, before the upper chambers with siCONT- and siNEDD4-treated cells (5 × 104 for each chamber). After 3 h, the cells through the membrane were fixed with 4% paraformaldehyde for 5 min and stained with 1% crystal violet in 2% ethanol. Pictures of the stained cells were taken by microscopy (Revolve, ECHO, San Diego, CA, United States).

Invasiveness ability was also tested using 8.0-μm-pore polycarbonate membrane-inserted transwell chambers (Corning, New York, NY, United States). The polycarbonate membrane of the upper chamber was coated with 0.3 mg/ml of matrigel, before the upper chambers with siCONT- and siNEDD4-treated cells (5 × 104 for each chamber). After 24 h, cells through the membrane were fixed with 4% paraformaldehyde for 5 min and stained with 1% crystal violet in 2% ethanol. Pictures of the stained cells were taken by microscopy (Revolve, ECHO, San Diego, CA, United States).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
