產(chǎn)品關(guān)鍵詞：

na?ve stem cells 初始干細(xì)胞；neural progenitor cells 神經(jīng)祖細(xì)胞；WH-4-023；CHIR99021；Stemfactor™ LIF；

產(chǎn)品描述：

Stemfactor™ Activin A是一種結(jié)晶級(jí)別的重組蛋白制備物，提供非常高的純度。激活素A（Activin A）具有雙重功能，不僅能維持干細(xì)胞潛能也能促進(jìn)分化。成熟的重組人激活素A是2條116個(gè)氨基酸殘基組成的βA亞基通過二硫鍵連接的二聚體，分子量約25kDa。

Stemgent公司提供支持初始潛能干細(xì)胞應(yīng)用需要的5i/L/A培養(yǎng)基添加劑（5i/L/A media supplment）所有成分，如下：

產(chǎn)品特性

1. 來源：E.Coli

2. 配方：Lyophilized from 20% acetonitrile

3. 氨基酸序列：GLECDGKVNI CCKKQFFVSF KDIGWNDWII APSGYHANYC EGECPSHIAG TSGSSLSFHS TVINHYRMRG HSPFANLKSC CVPTKLRPMS MLYYDDGQNI IKKDIQNMIV EECGCS

4. Uniprot序列號(hào)：P08476, residues 311-426

5. 純度：＞98%（SDS-PAGE）

6. 內(nèi)毒素水平：Less than 1.0 EU/μg of Activin A as determined by the LAL method.

7. 生物活性：The ED₅₀ is less than 6 ng/ml as determined by its ability to inhibit the proliferation of mouse MPC-11 cells.

8. 重溶：Centrifuge briefly and reconstitute Activin A in 10 mM HCl before dilution in cell culture medium. Avoid freeze-thaw cycles as it can result in loss of activity.

9. 保存和穩(wěn)定性：Activin A is shipped at room temperature. Lyophilized Activin A is stable for up to 6 months from date of receipt when stored at -20°C to -80°C.  Reconstituted Activin A, at concentrations greater than 0.1 mg/ml, is stable for up to 3 months when stored at -20°C and for 1 year when stored at -80°C
