The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
The interaction of bacterial and recombinant A-layer protein with murine macrophages was directed at determining the effect of A-protein on intracellular events that occur in primed macrophages. This was accomplished by measuring the cytotoxic product produced by peritoneal macrophages when exposed to A-protein coated latex beads. Thioglycolate elicited macrophages exhibited a low level of activation (18% cytotoxicity) that was significantly increased (48% cytotoxicity) in the presence of latex beads. Coating of the latex beads with each of the three A-protein products resulted in an increase of cytoxicity (mean +/- SEM) from 48% to 91%.

Preparation and Storage
Stability and Storage
Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
The protein was lyophylized in presence of NaHCO3 at 2:1 protein:salt ratio.
This product is an active protein and may elicit a biological response in vivo, handle with caution.
ReconstitutionReconstitute in sterile 0.4% NaHCO3.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Outer membrane protein A
RelevanceAeromonas salmonicida is the causative agent of goldfish ulcer disease. Virulence of this bacterium is associated with the production of a paracrystalline outer membrane A-layer protein also known as OmpA.
This protein comes from the gene for the monomeric form of OmpA from achromogenic atypical Aeromonas salmonicida.
