Recombinant Staphylococcus aureus Staphopain A (sspP) | CSB-EP305573FKZ | Cusabio

Alternative Name(s): Staphopain A(EC cysteine proteinase A)(Staphylopain A)

Gene Names: sspP

Research Areas: Cell Biology

Organism: Staphylococcus aureus


Source: E.coli

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

Expression Region: 215-388aa

Sequence Info: Full Length of Mature Protein

MW: 27.4 kDa

Purity: Greater than 90% as determined by SDS-PAGE.

Relevance: Cysteine protease that plays an important role in the inhibition of host innate immune response. Cleaves host elastins found in connective tissues, pulmonary surfactant protein A in the lungs, and the chemokine receptor CXCR2 on leukocytes (PubMed:3422637, PubMed:23235402). Proteolytic cleavage of surfactant protein A impairs bacterial phagocytocis by neutrophils while CXCR2 degradation blocks neutrophil activation and chemotaxis (PubMed:3422637, PubMed:23235402). Additionally, promotes vascular leakage by activating the plasma kallikerin/kinin system, resulting in hypotension (PubMed:15897280).

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.
