HKSA Heat Killed Staphyloccocus aureus HKSA is a lyophilized heat-killed preparation of Staphyloccocus aureus, a Gram-positive extra-cellular growing bacterium. HKSA is recognized mainly by TLR2. HKSA induces tolerance to a secondary HKSA stimulation but causes priming to LPS, suggesting a differential regulation of cytokines and chemokines in gram-positive- and gram-negative-induced inflammatory events. Specificity: TLR2 agonist Working concentration: 106-108 cells/ml Solubility: Insoluble (resuspended HKSA results in a cloudy suspension)
