ER-27319 (24 h) inhibits antigen-induced generation of inositol phosphates, release of arachidonic acid, and secretion of histamine and tumor necrosis factor α in RBL-2H3 cells, rat peritoneal and human cultured mast cells, and with IC50 value of 10 μM, approximately[1].
ER-27319 (10-30 μM, 10 min) selectivity inhibits the tyrosine phosphorylation of SYK induced by the phosphorylated immunoreceptor tyrosine-based activation motif of the FcεRI γ in RBL-2H3 cells[1].
ER-27319 (up to 100 μM, 60 min) does not inhibit the the tyrosine phosphorylation of ZAP-70 in response to anti-CD3 stimulation in the Jurkat cells[1].
ER-27319 (100 μM, 10 min) inhibits the tyrosine phosphorylation of two proteins (38, 70 kD) and decreases the tyrosine phosphorylation of the other two proteins (62, 80 kD) in anti-IgG stimulation Canine cutaneous mastocytoma-derived cells[2].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
