GAL-021
CAS No. : 1380341-99-0
MCE 国际站：GAL-021
产品活性：GAL-021 是一种有效的 BKCa 通道阻滞剂。GAL-021 抑制 GH3 细胞中的 KCa1.1。GAL-021 是一种基于对阿米替林药效团的选择性修饰的新型呼吸控制调节剂。GAL-021 增加大鼠和非人类灵长类动物的分钟通气量。
研究领域：Membrane Transporter/Ion Channel
作用靶点：Potassium Channel
In Vitro: GAL-021 is being developed as a novel breathing control modulator to preserve respiratory drive and protect patients from respiratory impairment due to opioids and other modalities. Using inside-out patches in GH3 cells, GAL-021 exerts concentration-dependent inhibition of single-channel KCa1.1 activity. When evaluated against 12 different cardiac ion channels, inhibition is 35% or less at 30 μM. No significant kinase inhibition is observed at 10 μM. At 30 μM in the radioligand binding assays, interactions (defined as >50% radioligand displacement) are detected at adenosine A1 (65% I), A2A (79% I, IC50 approximately 5μM), and A3 (93% I; IC50 approximately 1 μM) receptors, at 5-HT2B receptors (60% I; IC50 approximately 30 μM).
In Vivo: Intravenously administered GAL-021 attenuates opiate-induced respiratory depression in rats and nonhuman primates without affecting analgesia in rats. GAL-021 ventilatory stimulation in rats is attenuated by carotid sinus nerve transection. GAL-021 ventilatory stimulation is attenuated in mice lacking the pore-forming α-subunit of the KCa 1.1 channel.

文献和实验tianjiaoya 小弟最近要构建一个质粒，需要用到Gal4转录因子，有哪位大侠知道Gal4的UAS在那个质粒上？最好是容易买到的质粒啊，我查了好多质粒，都很难买到。或者能把Gal4的UAS的序列告诉我，这个上游激活序列应该不大，我可以去直接人工合成，然后参照别人那些构建成功的质粒的样子，把UAS插入到我的质粒中去，谢谢各位大侠了！！！ song333 GAL4/UAS system The GAL
Beta-gal Assay Adapted from Current Protocols in Molecular Biology 1. Grow 5ml YEPD cultures to mid-log phase. 2. Centrifuge and resuspend cells in 5ml Z-buffer, then place on ice. 3. Measure OD600. 4. Use straight
, transfect the DNA into mammalian cells, and then fix and stain a tissue with X-gal. The cells that turn blue must have the beta galactosidase enzyme, the product of the lac Z gene, which could only have been expressed from the donated promoter. Ergo
