Rabbit Anti-Human ANGPTL4 monoclonal antibody for ELISA, pep-ELISA, ICC, IF, WB. Angiopoietin-like protein 4 (ANGPTL4), is a secreted protein selectively expressed in adipose tissue, liver, and placenta1-3 that plays a variety of roles in vivo, ranging from adipogenesis to angiogenesis to carcinogenesis. The expression of ANGPTL4 is also under nutritional and hormonal control. ANGPTL4 has been observed to induce a strong pro-angiogenic response independent of vascular endothelial growth factor (VEGF), and its expression has been described in hypoxic human tissues as well as a variety of cancers, including liposarcoma, hepatocellular carcinoma, and conventional renal cell carcinoma.
