Tat-peptide control 168-189

Tat-peptide 168-189 is a cell-permeable Tat-tagged fusion peptide corresponding to residues 168-189 of rat G3BP1. The Tat sequence from HIV is incorporated at the least conserved end of this sequence to enhance cellular permeability. Serving as a negative control for Tat-peptide 190-208, Tat-peptide 168-189 contrasts with Tat-peptide 190-208, which promotes axon growth and increases the number of neurites per neuron.
