The nucleotide-binding domain and leucine-rich repeats containing proteins (NLRs) serve as immune receptors in both plants and animals. Overaccumulation of NLRs often leads to autoimmune responses, suggesting that the levels of these immune receptors must be tightly controlled. However, the

Mitochondria from diverse organisms are capable of transporting large amounts of Ca(2+) via a ruthenium-red-sensitive, membrane-potential-dependent mechanism called the uniporter. Although the uniporter's biophysical properties have been studied extensively, its molecular composition remains elusive. We recently used comparative proteomics to

ANTI-FLAG® M2 Magnetic Beads

The FLAG® Expression System is a proven method to express, purify and detect recombinant fusion proteins. Sigma®, the proven provider of FLAG®, now offers a magnetic bead for immunoprecipitation, protein purification, and the study of protein-protein interactions. The ANTI-FLAG® M2 Magnetic Bead is composed of murine derived, anti-FLAG® M2 monoclonal antibody attached to superparamagnetic iron impregated 4% agarose beads, with an average diameter of 50 µm. The M2 antibody is capable of binding to fusion proteins containing a FLAG peptide sequence at the N-terminus, Met-N-terminus, or C-terminus locations in mammalian, bacterial, and plant extracts.
