Solubility overviewSoluble in water to 10 mM and in 1 eq. NaOH 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.

ab12416 staining cGMP in SKNSH cells treated with 5,7-Dichlorokynurenic acid sodium salt (ab120254), by ICC/IF. Decrease in cGMP expression correlates with increased concentration of 5,7-Dichlorokynurenic acid sodium salt, as described in literature.
The cells were incubated at 37°C for 20 minutes in media containing different concentrations of ab120254 (5,7-Dichlorokynurenic acid sodium salt) in DMSO. Some samples where then further incubated with 15 µM NMDA (ab120052) for 5 minutes and all samples were fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with ab12416 (5 µg/ml) was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.
