Alpha Synuclein E114C Mutant Monomers: ATTO 488

Human Recombinant Alpha Synuclein E114C Mutant Monomers: ATTO 488

Product Specifications

Background

The alpha-synuclein (aSyn) E114C mutation facilitates a single site-specific conjugation with ATTO-488 maleimide that avoids any hindrance on fibrilization or cell entry that may be conferred by non-specific lysine targeting conjugations. This conjugation is ideal due to internal position relative to C-terminal truncation sites, proximity to the NAC, and lack of interference with recruitment in vitro or in primary neurons (1, 2) . Pre-formed fibrils (PFFs) generated with 5-25% fluorescently tagged E114C mutants have demonstrated a relative potency >80% compared to wild-type aSyn for inducing misfolding of endogenous aSyn, indicating no significant perturbation of seeding in living cells (1) . Atto-488 is a useful tool for identifying cell entry, as the addition of Trypan Blue to cultures prior to imaging will quench fluorescence of extracellular Atto-488 conjugated aSyn (3) . Our aSyn E114C-Atto-488 PFFs, which contain 10% fluorescently tagged E114C mutants, are an excellent tool for studying cell entry and localization, with demonstrated entry into neurons after trypan blue quenching.
