Mccoy s 5a modified medium

Manufactured by Corning

McCoy's 5a Modified Medium is a cell culture medium formulated to support the growth and maintenance of various cell lines. It provides the necessary nutrients, salts, and other components required for optimal cell proliferation and viability. The medium is a modification of the original McCoy's 5a formulation, which is widely used in cell biology research and applications.

Culturing Pre-Osteoblasts, U-2 OS, and HeLa

Check if the same lab product or an alternative is used in the 5 most similar protocols
Pre-osteoblast mouse cell line MC3T3-E1 subclone 4 (ATCC) was grown in alpha- Minimum Essential Medium (Gibco). U-2 OS and HeLa cells (ATCC) were grown in McCoy's 5a Modified Medium (Corning Cellgro) and DMEM, respectively. Cells were incubated at 37°C and 5% CO2.

U2OS human osteosarcoma cells were purchased from the American Type Culture Collection. These cells were maintained in McCoy’s 5A modified medium (Cellgro, 10-050-CV) supplemented with 10% FBS. Breast cancer MDA-AB-231 and HS578T cells were maintained in RPMI 1640 (Corning,10-040-CV) and DMEM (Corning, 10-017-CV) supplemented with 10% FBS. Cells were incubated at 37 °C in a humidified incubator with 5% CO2. Cells were irradiated with a RAD SOURCE RS-2000 X-ray irradiator (Suwanee, GA) at the indicated doses.

3D Colon Cancer Cell Proliferation

Check if the same lab product or an alternative is used in the 5 most similar protocols
In the study of cell proliferation and tumor growth in 3D, we chose a human colon cancer cell line HCT-116 (ATCC) as a cell model. Before loading the cells in the chip, we cultured them on tissue culture flasks in McCoy’s 5 A modified medium (Corning) with 10% (vol/vol) FBS (Gibco) and 1% penicillin/streptomycin (Gibco) at 37 °C and 5% CO2 in a humidified incubator. The cell culture medium was changed every other day and passaged when cells reached over 80% confluency. When the cells were embedded in 3D collagen, we continued culturing them by submerging the chip in fresh cell culture medium. Passage numbers of the cells used in this research did not exceed ten.

Mammalian Cell Culture and Plasmid Expression

Check if the same lab product or an alternative is used in the 5 most similar protocols
Human embryonic kidney HEK293T cells (CRL-3216) and human colorectal adenocarcinoma SW480 (CCL-228) and HCT116 cells (CCL-247) were obtained from American Type Culture Collection. HEK293T cells were maintained in DMEM (Corning) supplemented with 10% FBS (Gibco) at 37°C in a humidified, 5% CO2 incubator. HCT116 cells were maintained in McCoy’s 5a Modified Medium (Corning) supplemented with 10% FBS, while SW480 cells were maintained in Leibovitz’s L-15 Medium (Corning) supplemented with 10% FBS without CO2. Cell transfection was conducted with VigoFect (Vigorous Biotechnology) or Lipofectamine 2000 (Invitrogen).
All plasmids used in this study were generated by subcloning corresponding cDNAs into HA-pcDNA3.1 (for mammalian cell expression), pET32M.3C, pETMBP.3C (for bacteria expression), or pCS107-HA (for in vitro transcription) vectors. The sequences encoding human Axin1 (NCBI RefSeq no. NM_181050.3), human APC (NM_000038.6), human GSK3β (NM_001146156.2), β-catenin (NM_001098209.2), and human CK1α (NM_001025105.3) were amplified using standard PCR procedures with cDNA from HEK293T cells and subcloned into HA-pcDNA3.1, pETMBP.3C, and pCS107-HA vectors. Drosophila melanogaster dAPC2 (NM_001347814.1) was amplified and subcloned into pETMBP.3C vectors. Plasmids encoding Axin1 deletions or mutations were generated by PCR using primers with appropriate nucleotide substitutions.

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.
