L-Glutamic acid monosodium salt (Monosodium glutamate)
(Synonyms: 谷氨酸单钠盐) 目录号 : GC30788
L-Glutamic acid monosodium salt is the sodium salt of glutamic acid, found naturally in tomatoes, cheese and other foods. L-Glutamic acid monosodium salt acts as an excitatory transmitter and an agonist at all subtypes of glutamate receptors (metabotropic, kainate, NMDA, and AMPA). (S)-Glutamic acid shows a direct activating effect on the release of DA from dopaminergic terminals.
Cas No.:142-47-2
Sample solution is provided at 25 µL, 10mM.

Monosodium glutamate(MSG) induces apoptosis in human B cells. It has a more potent apoptotic effect in na?ve B cells compared to memory B cell population[3]. Low doses of L-monosodium glutamate promote neuronal growth and differentiation in vitro[4].
Daily monosodium glutamate(MSG) dietary consumption reduces pancreatic β-cell mass and enhances hemorrhages and fibrosis, but does not affect glucose homeostasis. High dietary MSG intake may exert a negative effect on the pancreas and such effect might become functionally significant in the presence or susceptibility to diabetes or NaCl. Parenteral MSG causes various changes in pancreatic islets such as hypertrophy, hyperplasia, decrease in acinar cells, α-cells and somatostatin cells and increase in fibrosis[1]. MSG may have some deleterious effects on the testes of Wistar rats and by extension may contribute to the causes of male infertility[2].

Animal experiment: |
For toxicity experiments, mice at PND9 (n=3-9 mice per group) are treated as follows. Two groups receive a subcutaneous (s.c.) injection of corn oil, following, 30 min later, by s.c. injection of either saline or L-Glutamic acid monosodium salt (3 g/kg); two additional groups are treated with 3,4-dihydro-2 H-pyrano[2,3-b]quinolin-7-yl-(cis-4-methoxycyclohexyl)-methanone, dissolving in corn oil (2.5 mg/kg) following, 30 min later, by a s.c. injection of either saline or L-Glutamic acid monosodium salt. In another set of experiments, four groups of crv4 mice or their wild-type littermates (n=5-7 mice per group) are injected s.c. with either saline or L-Glutamic acid monosodium salt (3 g/kg)[1]. |

DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
