Anti-PBF1 | 20S proteasome beta subunit F-1

PBF1 (20S proteasome beta subunit F-1) is a subunit of proteasome, multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. Alternative names: Proteasome subunit beta type-1, Proteasome component 5 Proteasome subunit beta type-6, TAS-F22/FAFP98, TAS-G39.20.

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.
