Annexin V, belonging to a recently discovered family of proteins, the annexins, with anticoagulant properties has proven to be a useful tool in detecting apoptotic cells since it preferentially binds to negatively charged phospholipids like PS in the presence of Ca2+ and shows minimal binding to phosphatidylcholine and sphingomyeline. Changes in PS asymmetry, which is analyzed by measuring Annexin V binding to the cell membrane, were detected before morphological changes associated with... - [Read Annexin V Protocol]
Tricine–SDS-PAGE Protocol and background. Nature. PDF file. Tricine–SDS-PAGE is commonly used to separate proteins in the mass range 1–100 kDa. It is the preferred electrophoretic
system for the resolution of proteins smaller than 30 kDa. –SDS-PAGE is also used preferentially for doubled SDS-PAGE (dSDS-PAGE), a proteomic tool used to isolate
extremely hydrophobic proteins for mass spectrometric identification. - [Read Tricine–SDS-PAGE Protocol PDF]
