Form
Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.

Target Background

Function
Alpha-toxin binds to the membrane of eukaryotic cells resulting in the release of low-molecular weight molecules and leading to an eventual osmotic lysis. Inhibits host neutrophil chemotaxis to the lesion region (Probable). Heptamer oligomerization and pore formation is required for lytic activity.
Gene References into Functions
  1. We now show that ADAM10 is critical for alpha-hemolysin-mediated activation of the NLRP3 inflammasome in human monocytes as siRNA knockdown or chemical blockade of ADAM10-alpha-hemolysin interaction leads to diminished inflammasome activation and cell death by reducing the available ADAM10 on the cell surface.

  2. Staphylococcus aureus hemolysin A disrupts cell-matrix adhesions in human airway epithelial cells. PMID: 24918472
  3. Succeeded in preparing crystals of the heptameric form of alpha-hemolysin without any detergent but with 2-methyl-2,4-pentanediol (MPD), and determined its structure. PMID: 21280135
  4. Staphylococcus aureus alpha-hemolysin activates the NLRP3-inflammasome in human and mouse monocytic cells PMID: 19826485
  5. The wide vestibule leading into the alpha-hemolysin pore helps to orient negatively charged synthetic alpha-helical peptides for translocation. PMID: 16866363
