L-Glutamine, 200 mM solution, tends to precipitate in solution when chilled. After thawing, it will be an opalescent solution. If allowed to settle, there can be some crystalline insolubles at the bottom of the bottle.The product should be warmed to 37°C for complete solubilization. To limit the number of times the product needs to be warmed to 37°C, the product can be divided into working aliquots which are stored at -20°C and used as needed. This will expose the product to the minimal amount of warming cycles.

General description
La L-glutamina es un aminoácido esencial que es un componente crucial de los medios de cultivo donde actúa como una fuente importante de energía para las células en cultivo. La L-glutamina es muy estable en forma de polvo seco y de disolución congelada. En los medios líquidos o las disoluciones de reserva, sin embargo, la L-glutamina se degrada con relativa rapidez. El rendimiento celular óptimo normalmente requiere el enriquecimiento de los medios con L-glutamina antes de su uso.
Application
The L-Glutamine solution has been used as a supplement in Roswell Park Memorial Institute (RPMI)-1640 medium to culture human leukemia monocytic cell line for intracellular assay and splenocytes for in vitro activation of CD4+ T cells. It has also been used as a supplement to the hybridoma medium used for primary screening for antigen binding and hybridoma cloning.
Preparation Note
Prepared in cell culture grade water.

Disruption of protein folding in the endoplasmic reticulum (ER) activates the unfolded protein response (UPR)-a signaling network that ultimately determines cell fate. Initially, UPR signaling aims at cytoprotection and restoration of ER homeostasis; that failing, it drives apoptotic cell death.

Is the molecular weight of L-Glutamine 146.14 or 146.15? The label information changed.
1 answer-
Based on a molecular formula of C5H10N2O3, the molecular weight to seven significant figures is 146.1456. Over the years, this value may have been reported in Sigma-Aldrich documentation or on labels as either 146.15 (by rounding up) or 146.14 (by truncation). The material itself has not changed.
