Anti-PAC1 | 20S Proteasome alpha subunit C1

PAC1 (20S Proteasome alpha subunit C1) is a component of proteasome complex which has ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The process is ATP-dependent. Alternative names: Proteasome subunit alpha type-4-A, 20S proteasome alpha subunit C-1, Proteasome 27 kDa subunit, Proteasome component 9, Proteasome subunit alpha type-3

Recommended western blot conditions:SDS-PAGE, transfer to nitrocellulose, blocking 10% non-fat milk. Diluent for both primary and secondary antibodies PBS containing 0.2% Tween 20 and 1% BSA.For an image of western blot detection, refer to:Smalleet al. (2002).

Store lyophilized/reconstituted at -20°C (short tem, months) or at -80°C (long term, years) ; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please remember to spin the tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tube.
