Plain liposomes are extensively used as artificial cell models and for studying the interaction of various types of molecules such as peptides and proteins with the surface of the lipid membranes. Plain liposomes are also used as control formulations for many different types of drug encapsulated liposome formulations. Charged liposomes are also used in many different types of blood complement studies. Plain liposomes are available in various anionic, cationic and neutral surface charges. Plain liposomes can be unilamellar or multilamellar.
DOTAP is a positively charged molecule and the products in Cellsome®-DOTAP-based catalog use DOPC as a matrix lipid and various amounts of cationic DOTAP lipid from 0.5% to 50% with various zeta potentials. If you are looking for DOTAP based liposomes for gene delivery, then you need to see the Genesome liposome catalog.
If you are looking for the cationic DOTAP-based liposomes for DNA/RNA delivery, please see Genesome® liposome catalog.

Bone Mesenchymal Stem Cells 作为一个细胞群体，还没有发现有特定细胞表面marker. 对于那些可以代表自我更新和分化的marker, 也不清楚到底要发现哪一个的表达才能确定该细胞就是BMSC。
目前常用的方法，就是采用培养，colony-forming unit-fibroblasts (CFU-F)这个方法。一般BMSC可以24-48小时贴壁。
流式细胞计数，比如STRO-1，但是一般认为STRO-1阳性的细胞更趋向于造血干细胞，和BMSC简单区别还不是很清楚。
这里有个培养分化的产品

下面的这段话是图注，图注的意思我明白，但是我想知道merge后的图看什么颜色的荧光，蓝色是细胞核，红色是lysosome(位于胞质），绿色是AMPKβ2，该实验是想观察AMPKβ2是否转位到lysosome上了，如果确实发生了AMPKβ2转位到lysosome上，那么merge后是红色与绿色融合在一起，是吗？融合在一起发什么颜色的光了？
