Pathway:

Mol. Weight:

38.5 kDa

Purity:

Greater than 85% as determined by SDS-PAGE.

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.

Research Areas:

Cancer

Function:

Secreted alkaline protease that allows assimilation of proteinaceous substrates. Acts as a significant virulence factor in invasive aspergillosis. Involved in immune evasion from the human and mice complement systems during infection. Efficiently cleaves important components of the complement cascade such as such as C3, C4, C5, and C1q, as well as IgG, which leads to down-regulation of complement activation at the hyphal surface.

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.

Protein Families:
