Galectin-9/LGALS9 Protein, Human (HEK293, His)

Galectin-9/LGALS9 Protein acts as an eosinophil chemoattractant, recruiting and migrating eosinophils, key immune cells in inflammatory responses. It also serves as an angiogenesis inhibitor, regulating blood vessel formation and impacting vascular processes. Functioning as a regulatory modulator, Galectin-9/LGALS9 suppresses interferon-gamma (IFNG) production by natural killer cells, exerting control over immune signaling pathways. Galectin-9/LGALS9 Protein, Human (HEK293, His) is the recombinant human-derived Galectin-9/LGALS9 protein, expressed by HEK293 , with C-6*His labeled tag.

Galectin-9/LGALS9 protein functions as an eosinophil chemoattractant, actively participating in the recruitment and migration of eosinophils, crucial immune cells involved in inflammatory responses. Moreover, it serves as an angiogenesis inhibitor, contributing to the regulation of blood vessel formation and impacting vascular processes. In its role as a regulatory modulator of immune responses, Galectin-9/LGALS9 suppresses interferon-gamma (IFNG) production by natural killer cells, exerting control over immune signaling pathways (By similarity).

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
