GsMTx4 生物活性

描述 GsMTx4 is a spider venom peptide that inhibits cationic mechanosensitive channels (MSCs). GsMTx4 is an important pharmacological tool for identifying the role of these excitatory MSCs in normal physiology and pathology[1][2]. GsMTx4 (2.5 μM, 16 h) significantly diminishes both the leptin-induced AMPK and MLC-2 phosphorylation in breast epithelial cells (MCF10A) [3]. GsMTx4 (500 nM, 48 h) attenuates demyelination induced by the cytotoxic lipid and psychosine (organotypic cerebellar slices). GsMTx4 (stereotactic injection, 3 μM of 1 μL, a single dose) is neuroprotective and inhibits lysophosphatidylcholine-induced astrocyte toxicity and demyelination in the cerebral cortex[4]. GsMTx-4 (intraperitoneal injection, 270 μg/kg for a single dose) reduces mechanical allodynia induced by inflammation and by sciatic nerve injury in Von Frey test[5].

溶解方案

DMSO: 50 mg/mL,配合低频超声助溶,注意:DMSO长时间开封后,会吸水并导致溶解能力下降,请避免使用长期开封的DMSO

H2O: 50 mg/mL,配合低频超声助溶

请根据您的动物给药指南选择适当的溶解方案。
以下溶解方案都请先按照体外实验的方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议现用现配,当天使用; 以下溶剂前显示的百分比是指该溶剂在终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶
