Cell Fractionation Antibody Sampler Kit #11843

Knowledge of the subcellular location of a protein may reveal the potential role it plays in a variety of cellular processes. Antibodies in the Cell Fractionation Antibody Sampler Kit can be used as a marker to ensure that each subcellular fraction is efficiently separated from the next. MEK1 and MEK2, also called MAPK or Erk Kinases, are dual-specificity protein kinases that function in a mitogen activated protein kinase cascade (1). Apoptosis-inducing factor (AIF) is a ubiquitously expressed flavoprotein that plays a critical role in caspase-independent apoptosis (2). Core histone protein, H3 is one of the primary building blocks of chromatin that makes up the nucleosome (3). Vimentin is a cell-specific intermediate filament with mesenchyme origin that contributes to making up of the cytoskeleton (4). MEK1/2, AIF, histone H3, and vimentin localize to the cytoplasm, mitochondria, nucleus, and cytoskeleton, respectively.
