生物活性

TAS-301 is an inhibitor of smooth muscle cell migration and proliferation, and inhibits PKC activation induced by PDGF.

IC50 & Target[1]

PKC

 

体外研究
(In Vitro)

TAS-301 (1-10 μM) concentration-dependently inhibits PKC activation and Ca2+ influx, induced by PDGF, with 62.7% inhibition on PKC activation at 10 μM, and reduces PMA-induced AP-1, with 38% and 67.6% inhibition at 3 and 10 μM, respectively[1]. TAS-301 (0.3-3 μM) dose-dependently reduces the migration of cells induced by growth factors (PDGF-BB, IGF-1,HB-EGF). TAS-301 (1-10 μM) also decreases bFGF-induced BrdU incorporation, especially at 3 and 10 μM[2].

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

体内研究
(In Vivo)

TAS-301 (3-100 mg/kg, p.o.) dose-dependently reduces the neointimal thickening and I/M ratio and decreases the level of intimal cells in rats 14 days after balloon injury[2].

Cell Assay
[2]

Cell proliferation is determined by the incorporation of BrdU by quiescent cells. SMCs are seeded at 1 × 104cells/well in 96-well plates in DMEM containing 10% FBS. Two days after the seeding, their growth is arrested for 3 days in a serum-free DMEM containing 5 μg/mL insulin, 5 μg/mL transferrin and 5 ng/mL sodium selenium (ITS). Then, the DMEM/ITS is removed, and serum-free DMEM containing 0.1% BSA with or without TAS-301 or tranilast is added to the quiescent cells 2 hr before treatment with the growth factor (i.e., bFGF 0.1 ng/mL). At 24 hr after stimulation, BrdU (10 μM) is added to the cells; 24 hr later, the cells are fixed. An ELISA is used to detect and to quantify the incorporated BrdU (n = 6). The drugs are present during the entire experiment[2].

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

Animal Administration
[2]

Rats[2]
On the 14th day after the balloon injury, the rats are anesthetized with ether so as to avoid any stress to the animals and then perfused transcardially with saline, followed by 10% buffered formalin. Next, the left carotid artery (length from aortic arch to bifurcation) is removed, postfixed and embedded in paraffin. Then, 3-μm-thick artery sections (six sections for each artery) are cut and stained with hematoxylin and eosin. The cross-sectional areas of the intima and the media on photographs are measured by use of a digital analyzer. The average of the ratio of the intimal area to the medial area in each artery is determined. Experimental groups are as follows: Vehicle (n = 9), TAS-301 (3, 10, 30 and 100 mg/kg,n = 9) and tranilast (100 and 300 mg/kg,n = 9). The data on two rats (one in TAS-301 100 mg/kg group and one in tranilast 100 mg/kg group) is omitted from the evaluation because of death due to faulty oral administration[2].

Help & FAQs
  • 冻干粉形式的重组蛋白如何溶解储存?

    1. 在打开盖子之前,先使用约 13000 rpm 的转速进行离心,20-30 s,将附着在管盖或管壁上的冻干粉收集到管底,以避免损失。 2. 以 10 μg 为例,先加 20 μL 我们赠送的复溶液,移液器吹打充分溶解。 3. 再加 80 μL 含载体蛋白(0.1% BSA, 5% HSA, 10% FBS, 或 5% 海藻糖中任一种)的缓冲液/培养基,移液器吹打混匀;最终浓度不低于 100 μg/mL。 4. 分装体积不少于 20 μL/管。 5. 分装后冻存于 -20ºC~-80ºC,可保存 3~6 个月。

  • 溶液形式的重组蛋白如何储存?

    1. 可以原产品储存,使用时再稀释。 2. 或者加含载体蛋白(0.1% BSA, 5, % HSA, 10% FBS, 或 5% 海藻糖中任一种)的缓冲液/培养基稀释,移液器吹打混匀,注意稀释后储存浓度不低于 100 μg/mL。 3. 分装体积不少于 20 μL/管。 4. 分装后冻存于 -20ºC~-80ºC,可保存 3~6 个月。

  • 为什么需要添加载体蛋白?

    载体蛋白通常被用于提高蛋白的稳定性,防止蛋白在冷冻或解冻过程中粘附在管壁上。离心管对蛋白有一定的吸附能力,这可能导致蛋白和管壁之间难以分离,导致溶液中蛋白的实际浓度下降,从而影响其活性。为减少这种损失,在长期保存重组蛋白产品之前,建议添加常用的载体蛋白溶液。

  • 载体蛋白种类和选择?

    0.1% BSA(牛血清白蛋白)、5% HSA(人血清白蛋白)、10% FBS(胎牛血清)或 5% 海藻糖,根据实验类型,若载体蛋白不影响研究结果,则可自选一种载体蛋白加到蛋白的储存液中。

  • 我收到的重组蛋白产品,什么也没看到,空空如也?

    冻干的体积大小受冻干前缓冲液组分、盐离子浓度、产品浓度等影响。由于工艺原因,蛋白冻干粉产品会呈现粉末状或肉眼不易观察到的透明薄膜状、胶冻状、雪花状,这些都是正常现象。此外,在运输过程中,冻干颗粒可能会分散,并粘附于瓶壁和瓶盖,肉眼无法清楚看到。收到产品后,请先离心,再按照冻干粉的重溶建议步骤,使用合适的缓冲液,重溶至说明书推荐的浓度,然后进行分装储存及使用。

  • 请问你们的重组蛋白都是有活性的吗?

    我们的重组蛋白可保证序列正确。至于蛋白是否有活性,取决于表达的序列是否包含活性区间。对于部分蛋白我们也会进行活性测试,并将数据公示于 COA 中。

  • 标签会对蛋白活性有影响吗?

    重组蛋白标签对蛋白的生物学活性影响存在未知结论,但对大部分检测应用中,重组蛋白的标签对蛋白本身生物学活性并无影响。MCE 对重组蛋白产品进行生物学活性检测,并将数据公示于 COA 中。
