Biological descriptionCell-permeable anti-inflammatory agent. Inhibits cyclooxygenases preventing prostaglandin formation. Inhibits components of the MAPK cascade, NF-κB and AP-1. Induces apoptosis through p38 MAPK activation.
Chemical name2-Hydroxybenzoic acid sodium salt
Storage instructionsStore at Room Temperature. Store under desiccating conditions. The product can be stored for up to 12 months.
Solubility overviewSoluble in water to 100 mM
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at an assay dependent concentration.

Functional Studies - Sodium salicylate (ab120746)
THP1 cells were incubated at 37°C for 40h with vehicle control (0 µM) and different concentrations of sodium salicylate (ab120746). Decreased expression of scavenging receptor SR-BI (ab52629) in THP1 cells correlates with an increase in sodium salicylate concentration, as described in literature.
Whole cell lysates were prepared with RIPA buffer (containing protease inhibitors and sodium orthovanadate), 10 µg of each were loaded on the gel and the WB was run under reducing conditions. After transfer the membrane was blocked for an hour using 5% BSA before being incubated with ab52629 at 1/2000 dilution and ab8227 at 1 µg/ml overnight at 4°C. Antibody binding was detected using an anti-rabbit antibody conjugated to HRP (ab97051) at 1/10000 dilution and visualised using ECL development solution.
