Check if the same lab product or an alternative is used in the 5 most similar protocols
The human monocytic cell line THP-1 cells (TIB-202) were purchased from ATCC. Cells were cultured in 24 well plates (Corning) and differentiated into THP-1 derived macrophages 24 hours prior to infection with 40 ng/mL phorbol 12-myristate 13-acetate (PMA) in RPMI 1640 Medium GlutaMAX™ Supplement (Gibco) at 37°C and 5% CO2. Experiments were realized within 15 passages and cell viability was measured before experiments by trypan blue exclusion and was greater than 97%. CD14+ primary human monocytes were extracted from peripheral blood of 5 healthy donors anonymously provided by the French Blood Establishment (EFS, Lyon). CD14+ monocytes were purified from whole blood using an autoMACS® Pro Separator, Whole Blood Column Kit and StraightFrom® Whole Blood CD14 MicroBeads (Mitenyi) according to the manufacturer’s instructions. Cell viability was measured before proceeding to macrophage differentiation, by trypan blue exclusion and was always greater than 80%. CD14+ monocytes were then plated in 24 well plates (Corning) at a density of 400 000 cells per well and differentiated into macrophages for 5 days prior to infection with 50 µg/ml Rh-GMCSF (Miltenyi) in RPMI 1640 Medium GlutaMAX™ Supplement (Gibco) with 10% FBS (Sigma-Aldrich) at 37°C, 5% CO2.

Primary murine myeloid cells flushed from femurs were isolated from female mice aged ~5 weeks, passed through a 100 μm-cell strainer (BD Falcon) and purified using the EasySep CD11b Positive Selection Kit (Stemcell). Murine bone-marrow derived CD11b+-myeloid cells were cultured on Poly-D-Lysine-coated (BD BioCoat) tissue culture plastic in Leibovitz’s L-15 medium (Life) supplemented with 10% v/v FBS (Thermo or PAA) and penicillin/streptomycin (Life) in an air incubator at 37°C. Human CD11b+-myeloid (34 (link)) monocytic-like THP-1 cells (TIB-202; passages #13-#19) were obtained from the American Type Culture Collection (ATCC) and maintained in RPMI1640 medium (PAA or Life) supplemented with 10% v/v FBS, 2 mM L-glutamine (Life) and penicillin/streptomycin in a humidified incubator at 37°C with 5% CO2. The intestinal epithelial cell line Caco-2 (HTB-37; #11-#15) was purchased from ATCC and maintained as described previously (35 (link)).

Evaluating Crystal-Induced Cytotoxicity in THP-1 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
THP-1 cells (TIB202), a human monocyte derived cell line, were obtained from the American Type Culture Collection (Manassas, VA). THP-1 cells were cultured in RPMI medium 1640 supplemented with 10% fetal bovine serum and 2-mercaptoethanol (0.05 mM) in T-75 flasks. For all experiments, cultured THP-1 cells were treated with CaOx, Cystine or CaP crystals (50, 100, 200, 500, 1000 µg/ml) or NaOx (0.1, 0.5, 1, 1.5, and 2 mM) and incubated at 37 °C in 5% CO2 for 24 h. Following treatment, cell viability was determined by the Trypan Blue exclusion assay. In brief, cells were treated with 0.4% Trypan Blue (1:1 dilution) and counted using the Countess Automated Cell Counter (Thermo Fisher Scientific Inc., Waltham, MA).

HEK293T (CRL-3216) cells and THP-1 (TIB-202) cells were purchased from ATCC. HEK293T cells were grown in Dulbecco’s modified Eagle’s medium (DMEM) with L-glutamine, 10% fetal bovine serum (FBS), and PenStrep 100 U/ml. THP-1 cells were grown in Roswell Park Memorial Institute (RPMI) medium 1,640 with L-glutamine and 10% FBS. All cells were grown at 37°C in a 5% CO2 atmosphere incubator. Cell lines were regularly tested for mycoplasma using the Universal mycoplasma detection kit (ATCC, #30-1012K).

HEK 293 (CRL-1573™) cells were obtained from American Type Culture Collection (ATCC, Manassas, MDVA, USA) and cultured in Dulbecco’s modified Eagle’s medium (Gibco™, Waltham, MA, USA; 11965118) with 10% fetal bovine serum (Gibco™, 16000044) and 1% antibiotic-antimycotic (Gibco™, 15240062) in a humidified atmosphere in a 5% CO2 incubator at 37°C. THP-1 (TIB-202) cells were obtained from ATCC and maintained in RPMI-1640 Medium (Gibco™, 21875034) containing 10% fetal bovine serum, 1% antibiotic-antimycotic and 0.05 mM 2-mercaptoethanol (Gibco™, 21985023). THP-1 cells were then stimulated with 50 nM phorbol myristate acetate (Sigma-Aldrich, St. Louis, MO, USA; P8139) for 24 h for induction of differentiation into macrophages.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Peripheral blood mononuclear cells (PBMCs) were purified from patient blood samples using Lymphoprep (Stemcell Technologies) and SepMate tubes (Stemcell Technologies, Vancouver, Canada). Lymphoprep was added to the lower compartment of the SepMate tube. Blood was mixed with PBS + 2% FBS in a 1 to 1 ratio, then layered on top of Lymphoprep following the company protocol. Samples were centrifuged at 800g for 20 min at 18°C with the brake off. The upper plasma layer was discarded. The PBMCs layer was removed carefully then washed with PBS and centrifuged at 300g for 8’ at room temperature between each wash. The pellet was stored at -20°C or isolated PBMCs used immediately following the experiments. 10X106 fresh lymphocytes sample, ID W313715036917, was received from HemaCare Corporation (Van Nuys, CA, USA). THP-1(TIB-202) cells were purchased from ATCC (Manassas, VA, USA) and maintained following the manufacture protocol. PBMCs and THP-1 cells were treated with human recombinant proteins rhGCase or rhα-Gal A, rapamycin (RAP), or a combination of RAP and 3MA in phenol red-free RPMI media with 10% FBS.

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.
