  • Just like the SURFE 2 R N1, the SURFE 2 R 96SE employs solid supported membrane (SSM)-based electrophysiology to resolve small currents of transporters and pumps but elevates the throughput to the next level by parallelization of 96 measurements. (nanion.de)
  • Syntaxin 2 localizes to the apical plasma membrane and regulates epithelial-mesenchymal interactions. (enzolifesciences.com)
  • Several events contribute to NRF1 and NRF2 activation, among them the proteolytic cleavage of NRF1 from the ER membrane and the phosphorylation of NRF2. (hindawi.com)
  • Cleavage of anchored proteins with exogenous PIPLC has been achieved in a variety of culture media or isotonic buffers. (elsevierpure.com)
  • C3 cleavage may result in formation of the membrane attack complex (MAC), the cytotoxic component of the complement system. (msdmanuals.com)
  • This assembly results in a spontaneous, essentially traceless splicing reaction that covalently links the two flanking protein segments through native chemical ligation 9 . (biorxiv.org)
  • The prototypical example of a protein that is covalently attached to other proteins is ubiquitin, but in recent years, evidence for at least a dozen such systems has come to light. (yale.edu)
  • The latter facilitates the simultaneous use of two orthogonal split inteins within the same peptide or protein, an approach termed tandem protein trans-splicing (tPTS). (biorxiv.org)
  • Semi-synthetic approaches offer an alternative means to manipulate proteins post-translationally, but these modifications have typically been performed in vitro 3 - 8 . (biorxiv.org)
  • CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. (rndsystems.com)
