CAS 67-42-5: EGTA
Descrizione:
EGTA, o acido etilenoglicol tetraacetico, è un agente chelante comunemente usato in biochimica e biologia molecolare. Ha la capacità di legarsi a ioni metallici bivalenti, come calcio e magnesio, il che lo rende particolarmente utile in varie applicazioni sperimentali, inclusi saggi enzimatici e purificazione delle proteine. EGTA è un solido cristallino incolore solubile in acqua, e la sua struttura presenta quattro gruppi di acido acetico attaccati a uno scheletro di etilenoglicole, permettendogli di formare complessi stabili con ioni metallici. Il pH delle sue soluzioni può influenzare significativamente la sua capacità chelante, con prestazioni ottimali tipicamente osservate in condizioni neutre o leggermente alcaline. A causa della sua forte affinità per gli ioni di calcio, EGTA è spesso impiegato in studi che coinvolgono la segnalazione del calcio e i processi cellulari. Inoltre, è importante maneggiare EGTA con cura, poiché può interferire con alcune reazioni biochimiche sequestrando ioni metallici essenziali. In generale, EGTA è uno strumento versatile nella ricerca, fornendo informazioni critiche sulle interazioni degli ioni metallici nei sistemi biologici.
