Anti-CASP3 Intrabody [Tat] (IAB-B002(T))
Recombinant anti-CASP3 intrabody in fusion with HIV Tat works within cells and specifically binds to pro-apoptotic protein CASP3, expressed in CHO cells. These intrabodies are useful drugs on their own as well as a means for identifying small compound drugs for degenerative diseases involving oxidative-stress-induced apoptosis.

TAT was able to deliver different proteins, such as horseradish peroxidase and RNase A across cell membrane into the cytoplasm in different cell lines in vitro. The size range of proteins with effective delivery is from 30kDa to 120-150kDa. In one study, TAT-fused proteins are rapidly internalized by lipid raft−dependent macropinocytosis using a transducible TAT−Cre recombinase reporter assay on live cells. In another study, a TAT-fused protein was delivered into mitochondria of breast cancer cells and decreased the survival of breast cancer cells, which showed capability of TAT-fusion proteins to modulate mitochondrial function and cell survival. However, very few in vivo studies have succeeded. In one study, in vivo delivery of TAT- or penetratin-crosslinked Fab fragments yielded varied organ distributions and an overall increase in organ retention, which showed tissue localization.
