6 well ultra low cluster plates

Manufactured by Corning
Sourced in United States

The 6-well ultra-low cluster plates are a laboratory equipment product designed for cell culture applications. The plates feature a hydrophobic surface that promotes the formation of 3D cell aggregates, also known as spheroids or organoids. This specialized surface minimizes cell attachment and encourages the cells to self-assemble into cellular clusters, which is useful for various research and development purposes.

Cells (500 cells/well) were seeded into 6-well ultra low cluster plates (Corning) and cultured as previously described.45 (link) After 10–12 days, the number of cell spheroids (tight, spherical, non-adherent masses >50 μm in diameter) were counted, and images of the spheroids were scored under an inverse microscope (spheroid formation efficiency = colonies/input cells × 100%).

Cells (500 cells/well) were seeded into 6-well Ultra Low Cluster plates (Corning) and cultured as previously described [36 (link)]. After 10–12 days, the number of cell spheroids (tight, spherical, non-adherent masses > 50 μm in diameter) were counted, and images of the spheroids were scored under an inverse microscope (spheroids formation efficiency = colonies/input cells× 100%).

The LSR II flow cytometer (BD Pharmingen, San Diego, CA, USA) was used to analyze and separate CSCs based on cell labeling and fluorescence-activated sorting. The activated ALDEFLUOR™ reagent and diethylaminobenzaldehyde purchased from Stemcell Technologies, Inc. (Vancouver, BC, Canada) were used to isolate aldehyde dehydrogenase (ALDH)+ cells (21 (link)–23 (link)). The ratios of ALDH1+ stem cells in different groups were analyzed. The ratios of aldH 1+ stem cells in different groups were analyzed. For sphere forming assay, CSCs (1000cells per/ well) were seeded in 6-well ultra-low cluster plates (Corning Inc., Corning, NY) for one week to obtain first generation after being given different treatment. Spheres were cultured in DMEM/F12 serum-free medium (Invitrogen) supplemented with 2% B27 (BD Biosciences, CA), 20ng/ml epidermal growth factor (EGF, Sigma), 20ng/ml basic fibroblast growth factor (bFGF, Sigma), 0.4% BSA and 4 μg/ml insulin (Sigma). The number of spheres was counted under a microscope.

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.
