General description

Membrane proteins make up around 20-30% of an organism′s genome and serve as cellular gatekeepers, regulators, and sensors. They have diverse cellular functions, such as shielding the cell from external toxins, being the starting point of intracellular signaling cascades, and retaining critical ion concentrations.


The kit offers a fast and convenient method to isolate hydrophobic and raft microdomain associated proteins from cells. The method is based on phase separation and does not require cell membrane isolation. The separated proteins can be used for further experiments such as SDS-PAGE, Western blotting, dot blotting, and immunoprecipitation. The kit has been tested on, but not limited to, HeLa, HEK-293, NIH 3T3, COS and CHO cell lines.


Sufficient reagents supplied for 80 tests.

Membrane protein structural biology is still a largely unconquered area, given that approximately 25% of all proteins are membrane proteins and yet less than 150 unique structures are available. Membrane proteins have proven to be difficult to study owing to...

Angiogenesis is a necessary process for solid tumor growth. Cellular markers for endothelial cell proliferation are potential targets for identifying the vasculature of tumors in homeostasis. Here we customize the behaviors of engineered cells to recognize Apj, a surface marker...

The functional significance of the expression of cystic fibrosis transmembrane regulator (CFTR) on endothelial cells has not yet been elucidated. Since CFTR has been implicated in the regulation of intracellular sphingolipid levels, which are important regulators of endothelial cell apoptosis...
