S-9 大鼠肝匀浆/致突变性试验用（Ames试验用）

Ames Test-Rat liver 9,000×g supernatant fraction

◆「S-9」调配方法

　　将雄性大鼠饲养与SPF环境下，养至7周大小（体重180g-200g）后，把诱导剂Phenobarbital（PB）和5, 6-Benzoflavone（BF）投与大鼠肝脏。

　　PB是在剖杀前4天连续每天投注，BF则是剖杀前2天投注一次。然后无菌摘取大鼠肝脏，匀浆后9000xg离心，收集S-9上清。调配方法以Ames方法为准。

  AteloCell™ Atelocollagen，Native collagen牛皮源去端肽胶原

◆原理

Cosmo Bio公司以先进的产品技术，优良的质量监控为广大客户提供用于细胞培养的胶原溶液。

Atelocollagen (端胶原)(IPC)：胃蛋白溶解I型胶原溶液

Native collagen（天然胶原）(IAC)：酸溶解I型胶原溶液

◆优点・特色


所有产品均已灭菌。胶原蛋白从牛的真皮中提取，经过新颖的方法进行溶解纯化。在37℃，端胶原与天然胶原会形成纤维。

 

◆案例・应用


胶原包被在培养皿上；细胞在胶原上三维培养



35mm胶原海绵培养皿

◆原理

胶原海绵细胞培养是以胶原蛋白为基础新开发出来的，可用于细胞3D培养。多孔胶原海绵是由牛跟腱提取的不溶性I型胶原蛋白制备而成。细胞可渗透入海绵，朝不同方向增殖。

◆优点・特色

Atelocollagen, Permeable membrane for50mmculture dish

◆原理

从牛跟腱中提取的I型胶原蛋白制备的可渗透性胶原蛋白膜可用于单层或双层细胞培养。此胶原蛋白膜特别适用于研究在膜两侧培养的不同细胞间的分子相互作用，相互关系。膜的可渗透性允许氨基酸，蛋白质等小分子自由通过胶原蛋白膜，这对于细胞间的营养吸收，物质交换有重要作用。

◆优点・特色


●　两种不同细胞可在膜两侧生长，因此特别适合研究细胞或小分子相互间的作用。

●　可渗透性膜非常适合细胞培养，也适合人工皮肤，人工胰腺等其它人工器官的培养。

Atelocollagen, Honeycomb sponge

◆原理

“蜂窝状”海绵的结构比较特殊，它的孔径大约200-400μm，密集地向一个方向排列，因此细胞可以顺着小孔渗透增殖。这样的结构，有利于海绵内部的细胞吸收营养物质，排出生物代谢物质。细胞在空腔内增殖，并形成统一的细胞团。

优势：从牛跟腱中提取胶原蛋白制备“蜂窝状”海绵，可以用胶原酶降解此海绵。

AG310-30MG | FLUORO-JADE® B

merck millipore,默克密理博 AG310-30MG | FLUORO-JADE® B

Description
Catalogue Number AG310-30MG
Trade Name
  • Fluoro-Jade
Description FLUORO-JADE® B
Overview N-terminal GST-tagged, recombinant human XIAP full length, expressed by baculovirus in Sf21 insect cells
Background Information Fluoro-JadeⓇ B is a polyanionic fluorescein derivative which sensitively and specifically binds to degenerating neurons. It is a dark red power that has a green iridescence with excitation peak at 480 nm and emission peak at 525 nm. The filter used for visualizing Fluoro-JadeⓇ B is a fluorescein/FITC filter. Fluoro-JadeⓇ B can be used on most tissue section types and thicknesses including frozen, vibratomed cryostat or paraffin-embedded sections from 3-50 µm. Fluoro-JadeⓇ B is faster and more reliable than older methods (e.g. suppressed silver) for the unequivocal qualitative detection and quantitative measurement of both and fine scale neuronal degeneration.

Product Information
Formulation
Presentation Solubility: Very soluble in water and bases, moderately soluble in alcohol and weak acids.
