生物活性

Apamin (Apamine) is an 18 amino acid peptide neurotoxin found in apitoxin (bee venom), is known as a specifically selective blocker of Ca-activated K (SK) channels and exhibits anti-inflammatory and anti-fibrotic activity.

体外研究(In Vitro)

Apamin (0.5-2 μg/mL; 24 hours; HSC-T6 cells) treatment markedly reduces the expression of α-SMA in the TGF-β1-induced HSC-T6 cells. Apamin treatment abrogats the activation of p-Smad2/3 and Smad4 induced by TGF-β1.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis

Cell Line:	HSC-T6 cells
Concentration:	0.5 μg/mL, 1 μg/mL and 2 μg/mL
Incubation Time:	24 hours
Result:	Markedly reduced the expression of α-SMA in the TGF-β1-induced HSC-T6 cells. Abrogated the activation of p-Smad2/3 and Smad4 induced by TGF-β1.

体内研究(In Vivo)

Apamin (0.1 mg/kg; intraperitoneal injection; twice a week; for 4 weeks; C57BL/6 male mice) treatment results in decreased liver injury and proinflammatory cytokine levels. Apamin suppresses the deposition of collagen, proliferation of BECs and expression of fibrogenic genes in the 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC)-fed mice.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	8-week-old C57BL/6 male mice (20-25 g) with DDC feeding
Dosage:	0.1 mg/kg
Administration:	Intraperitoneal injection; twice a week; for 4 weeks
Result:	Resulted in decreased liver injury and proinflammatory cytokine levels. Suppressed the deposition of collagen, proliferation of BECs and expression of fibrogenic genes in the DDC-fed mice.

产品使用指南

Data Sheet

1：一般建议：溶解度为Medlife测试数据，可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解，请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异，仅做参考，具体以实验方案为准。

2：储存条件：粉末-20°C一般情况可以保存3年，溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异，请细致阅读产品信息，并辅助参考相关文献描述。
