Source: E.coli

Tag Info: N-terminal 10xHis-tagged and C-terminal Myc-tagged

Expression Region: 23-319aa(E189K)

Sequence Info: Full Length of Mature Protein

MW: 40.6 kDa

Purity: Greater than 85% as determined by SDS-PAGE.

Relevance: The A subunit is responsible for inhibiting protein synthesis through the catalytic inactivation of 60S ribosomal subunits. After endocytosis, the A subunit is cleaved by furin in two fragments, A1 and A2: A1 is the catalytically active fragment, and A2 is essential for holotoxin assembly with the B subunits. Catalytic activity Endohydrolysis of the N-glycosidic bond at one specific adenosine on the 28S rRNA. EC:3.2.2.22

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.

Form: Liquid or Lyophilized powder

Buffer: If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Reconstitution: We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
