Acalabrutinib (Calquence) maleate is an orally active, irreversible, and highly selective second-generation BTK inhibitor. Acalabrutinib binds covalently to Cys481 in the ATP-binding pocket of BTK. Acalabrutinib maleate demonstrates potent on-target effects and efficacy in mouse models of chronic lymphocytic leukemia (CLL). Acalabrutinib maleate can be used for CLL research. Acalabrutinib maleate is a click chemistry reagent, which contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
