The human pancreatic cancer cell lines MIA PaCa-2, AsPC-1, PANC-1 and BxPC-3 were purchased from American Type Culture Collection (CRL-1420TM, CRL-1682, CRL-1469 and CRL-1687, respectively, ATCC; Rockville, MD, USA) and banked at Centre Paul Strauss. Cells were cultured at 37 °C in a humidified atmosphere containing 5% CO2 and 95% air. PANC-1 was cultured in Dulbecco’s modified Eagle’s medium (DMEM; PAN Biotech GmbH, Aidenbach, Germany) supplemented with 10% fetal bovine serum (FBS, PAN Biotech GmbH) and 1% of a solution of penicillin (10000 IU/mL) and streptomycin (10 mg/mL) (PAN Biotech GmbH). MIA PaCa-2 was cultured in the same conditions with 1% of 4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid (HEPES, 1 mM, PAN Biotech GmbH), 1% of sodium pyruvate (10 mM, PAN Biotech GmbH) and 1% of non-essential amino acids (NEAA, PAN Biotech GmbH). AsPC-1 and BxPC-3 were cultured in Roswell Park Memorial Institute medium (RPMI; PAN Biotech GmbH) supplemented with 10% FBS, and 1% of a solution of penicillin (10000 IU/mL) and streptomycin (10 mg/mL). Subconfluent cell monolayers were trypsinized once a week using 0.5% trypsin containing 2% EDTA (PAN Biotech GmbH) and plated at passage ratios between 0.25:10 to 1:10, according to the cell line or used directly for study after enumeration determined with a Countess® Cell Counter (Countess, Invitrogen, Carlsbad, CA, USA).

Culturing Cancer Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
CT-26 (murine colon cancer), HCT-116 (human colon cancer), CRL-1739 (human stomach gastric cancer) and CRL-1682 (human pancreatic cancer) cell lines were purchased form ATCC. All cells were cultured in T-75 flasks (Falcon). All media were purchased from Life Technologies and supplemented with 10% fetal bovine serum (Sigma) and 1% penicillin-streptomycin (Fisher Scientific). CT-26 and CRL-1682 were cultured in RPMI-1640 medium. CRL-1739 and HCT-116 were cultured in DMEM medium. All cells were cultured in a 37° C, 5% CO2 incubator.

Culturing Human Pancreatic and Leukemia Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Pancreatic human cell line was purchased from ATCC (LGC Standards, Molsheim, France). Cells were kept at 37 °C in humidified atmosphere containing 5 % (v/v) CO2 during their exponential growing phase and during incubation with investigated compounds. Confluency adherent cells were trypsinized and sub-cultured twice a week. Human pancreatic (AsPC-1, ATCC® CRL-1682) cell lines were maintained in DMEM high glucose medium (Dominique Dutscher, 67172 Brumath, France, Cat No L0102-500), while human acute monocytic leukemia cell line (THP-1, ATCC® TIB-202) was maintained in RPMI-1640 medium (ATCC® 30-2001™, LGC Standards S.a.r.l., Molsheim, France), supplemented with 10% (v/v) heat-inactivated fetal bovine serum (FBS, Life Technologies, Paisley, UK, Cat No 10270-106) and 1% (v/v) penicillin–streptomycin (105 units/mL and 10 mg/mL, Life Technologies, Paisley, UK, Cat No 15140-122).

Cell Line Maintenance Protocol

All human cell lines purchased from ATCC (LGC Standards, Molsheim, France) Human mammary (MCF-7, ATCC® HTB-22), pancreatic (AsPC-1, ATCC® CRL-1682) and colon (SW-620, ATCC® CCL-227) adenocarcinoma cell lines were maintained in DMEM high-glucose medium (Dominique Dutscher, 67,172 Brumath, France, Cat No L0102-500), while the human acute monocytic leukemia cell line (THP-1, ATCC® TIB-202) was maintained in RPMI-1640 medium (ATCC® 30-2001™, LGC Standards, Molsheim, France), supplemented with 10% (v/v) heat-inactivated fetal bovine serum (FBS, Life Technologies, Paisley, UK, Cat No 10270-106) and 1% (v/v) penicillin-streptomycin (10,000 units/mL and 10,000 µg/mL, Life Technologies, Paisley, UK, Cat No 15140-122). Cells were kept at 37 °C in a humidified atmosphere containing 5% (v/v) CO2 during their exponential growing phase and in the course of incubation with investigated compounds. Before confluence, adherent cells were trypsinized and sub-cultured twice a week.
Investigated extracts were initially dissolved in dimethyl sulfoxide (DMSO) in a concentrated stock solution. Further dilutions to the experimental concentrations applied on the cells have been done in RPMI-1640 or DMEM media prior to each experiment, thus the final concentration of DMSO on treated cells was 0.5% (v/v) for the most applied concentrations.

Human carcinoma cells of breast [MDA-MB-231 (ATCC® HTB-26)], prostate [LNCaP clone FGC (ATCC® CRL-1740)], and pancreas [AsPC-1 (ATCC® CRL-1682)] origin were obtained from American Type Culture Collection (ATCC) and cultured in medium designated by the provider for propagation and maintenance. All cell lines were used at low passage number and proven free of Mycoplasma.

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.
