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.
Tat-peptide 190-208 TFA (10 μM, 20 μM; 24 h) increases axon length in dissociated DRG cultures with 10 μM, as well as in iMotor neurons with 20 μM[1].
Tat-peptide 190-208 TFA (10 μM; 3 d) increases the overall number of neurites extended from each neuron[1].
