Rpmi 1640 l glutamine medium

Manufactured by Thermo Fisher Scientific
Sourced in United States, Belgium

RPMI 1640 + L-glutamine medium is a cell culture medium formulated to support the growth and maintenance of a variety of cell lines. It provides a balanced salt solution, amino acids, vitamins, and other essential nutrients required for cell proliferation. The addition of L-glutamine, a critical nutrient, further enhances the medium's ability to sustain cellular metabolism and growth.

Heparinized blood was diluted with L-glutamine-RPMI 1640 medium (Life
Technologies, Grand Island, NY) at a 1:1 ratio and stimulated with organic dust
extract (1%), triacyl lipopeptide N-palmitoyl-S-dipalmitoylglyceryl
Cys-Ser-(Lys)4 (Pam3CSK4, 1 ng/ml), peptidoglycan (PGN, 10
µg/ml) or phosphate buffered saline. Blood was incubated for 24 hr at
37°C with 5% CO2, and then centrifuged at 500
× g for 5 min. Cell-free supernates were stored at −80°C
for later cytokine analysis. Blood samples were processed within 2 hr of
collection.

The androgen-sensitive human prostate adenocarcinoma cell line LNCaP was purchased from the American Type Culture Collection (ATCC) and cultured in RPMI 1640 (+) L-Glutamine medium from Gibco Life Technologies (Thermo Fisher Scientific, Waltham, MA) supplemented with 10% fetal bovine serum, 100 units/ml penicillin-streptomycin, and mM sodium pyruvate. This line was authenticated regularly in our institutional CCSG Cell Line Characterization Core and also examined to be free of mycoplasma contamination. Cells were maintained in 5% CO2 at 37C and cultured in 10 cm plates to a confluency of 70-80% before fixation. LNCaP cells were fixed in 1% methanol-free formaldehyde (Thermo Fisher Scientific) in RPMI for 10 min at room temperature followed by quenching for 5 min in mM glycine (Sigma, St. Louis, MO) with low-speed shaking on an orbital platform. Plates were washed 2× with ice-cold phosphate-buffered saline (PBS) (pH 7.4) (Thermo Fisher Scientific) to eliminate any residual media, and 7 ml cold PBS containing 1× Complete Protease Inhibitors Cocktail, EDTA free (Roche, Basel, Switzerland) were immediately added. Plates were kept on ice while the cells were harvested by scraping. Cells were transferred to 15 ml conical tubes (2 plates/tube) and collected by centrifugation (4 min at 805 × g at 4°C). Cells were immediately used for chromatin preparation.

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.
