Ac-I3K-NH2

Ac-I3K-NH₂ is a surfactant-like peptide. Ac-I3K-NH₂ self-assembles into β-sheet nanofibers through β-sheet hydrogen bonding, hydrophobic interactions, and electrostatic repulsion. Ac-I3K-NH₂ forms ribbon-like nanofibers with nanoscale widths, adopting a β-sheet conformation, with lateral stacking driven by isoleucine side-chain contacts. Ac-I3K-NH₂ templates the sol-gel condensation of tetraethoxysilane, producing silica nanotubes. Ac-I3K-NH₂ templates the synthesis of one-dimensional Pt nanostructures with P7A as a capping agent.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
