Anti-SPESP1 Antibody

This Antibodies.com primary antibody targets SPESP1 (Sperm Equatorial Segment Protein 1), a testis-expressed transmembrane glycoprotein localized to the equatorial segment of mature spermatozoa and implicated in sperm-egg membrane fusion during fertilization. The polyclonal reagent is raised in rabbit and purified as an IgG preparation, supplied unconjugated in liquid format at 100 µl per vial. It has been validated for western blot and immunofluorescence applications on mouse samples, making it useful for reproductive biology studies of acrosome biogenesis, spermatid maturation, and fertilization competence. For best results, store the antibody frozen at -20 °C in small aliquots to limit freeze-thaw cycles and protect the protein from degradation. This reagent is intended for research use only and is not validated for diagnostic or therapeutic use.
