Cell migration was evaluated by a wound-healing assay. Cells were plated in six-well dishes and the cell monolayers were scraped using a P-20 micropipette tip. Wound closure was monitored and the percent closure was measured. A cell invasion assay was carried out using modified Boyden Chambers consisting of transwell-precoated Matrigel membrane filter inserts with eight micro pores in 24-well tissue culture plates (BD Biosciences, Bedford, MA, USA). Cells were re-suspended in culture medium without FBS and placed in the upper chamber in triplicate. After 48 h incubation at 37 °C, cells migrating through the membrane were stained. The results were expressed as invaded cells quantified at OD 560 nm.

Cell Migration and Invasion Assay

Check if the same lab product or an alternative is used in the 5 most similar protocols
Cell migration was evaluated by a wound-healing assay. Cells were plated in six-well dishes and after VCAN siRNA treatment for 48 hours, monolayers were scraped using a P-20 micropipette tip. The width of the initial gap (0 hour) and the residual gap 16 or 24 hours after wounding were calculated using a Nikon Eclipse TS100 microscope (Technical Instruments, Burlingame CA). Cell invasion assay was carried out using modified Boyden chambers consisting of transwell-precoated Matrigel membrane filter inserts with 8 µm pores in 24-well tissue culture plates (BD Biosciences, Bedford, MA). Transfected cells were re-suspended in culture medium without FBS and placed in the upper chamber. After 24 hours incubation at 37°C, cells migrating through the membrane were stained. The results were expressed as invaded cells quantified at OD 560 nm using a SPECTRA MAX 190 plate reader.

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.
