Recombinant Anti-human FOLR1 Intrabody [Tat]

CAT#: IAB-B029(T)

Recombinant anti-FOLR1 intrabody in fusion with HIV Tat works within cells to bind FOLR1, which is selectively overexpressed in 90% of nonmucinous ovarian carcinomas, expressed in CHO cells. FR expression is associated with tumor progression and affects cell proliferation and the intracellular expression of single-chain (sc) antibodiess (intrabody) can downmodulate membrane expression of FR in ovary cancer cells.

    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.
