Tat-peptide 190-208 TFA is a cell-permeable and Tat-labeled fusion peptide, corresponding to residues 190-208 of rat G3BP1. Tat sequence from HIV, is placed at the least conserved end of the sequence, for cell permeability. Tat-peptide 190-208 TFA increases axon growth and increases the number of neurites per neuron. Tat-peptide 190-208 TFA likely exhibits an axon intrinsic mechanism. Tat-peptide 190-208 TFA can be used for ischemic protection during endovascular repair for intracranial aneurysms.
