The Kilon/NEGR1 protein has been implicated in cell adhesion, suggesting a role in important cellular interactions. Its potential function as a transneuronal growth-promoting factor highlights its dynamic role in promoting regenerative axonal sprouting in the mammalian brain. Kilon/NEGR1 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Kilon/NEGR1 protein, expressed by HEK293 , with C-His labeled tag.
