Sec8 Antibody (LB-2) is a mouse monoclonal IgG2a antibody that detects Sec8 in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), and enzyme-linked immunosorbent assay (ELISA). Sec8, also known as EXOC4, REC8, or SEC8L1, is a critical component of the exocyst complex, which plays a vital role in exocytosis, a process essential for membrane trafficking, hormone and neurotransmitter secretion, and the incorporation of membrane proteins and lipids into the plasma membrane. The exocyst complex, composed of eight protein subunits including Sec3, Sec5, Sec6, Sec8, Sec10, Sec15, Exo70, and Exo84, is crucial for targeting exocytic vesicles to specific docking sites on the plasma membrane, thereby facilitating effective cell-cell communication, cell growth, and maintaining cell polarity. Notably, Sec8 is involved in modulating microtubule dynamics, as Sec8 has been shown to inhibit tubulin polymerization in vitro, highlighting Sec8′s importance in the regulation of cytoskeletal elements that underlie exocytosis. Human Sec8 is located on chromosome 7q33, and Sec8′s proper functioning is essential for various cellular processes, making anti-Sec8 antibody (LB-2) a valuable tool for researchers studying exocytosis and related cellular mechanisms.
