Activité biologique
MK-28 (0-100 μM) shows PERK selectivity in vitro on a 391-kinase panel and rescues cells (but not PERK / cells) from ER stress-induced apoptosis[1].
ATF4 protein levels are increased signifcantly, up to 2.5-fold, in STHdhQ111/111 cells at high MK-28 concentration. CHOP and GADD34 mRNA levels show a signifcant increase in both cell types, up to 10- and 5-fold respectively[1].
MK-28 has little or no efect on EIF2AK1 (HRI) or EIF2AK2 (PKR), but it activats EIF2AK4 (GCN2)[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

MK-28 (1 mg/kg, IP, daily for 28 days) improves systemic function and survival in R6/2 mice and induces increased levels of eIF2α-P in the mouse brain striatum[1].
MK-28 (Transient subcutaneous delivery) significantly improves motor and executive functions and delayed death onset in R6/2 mice, showing no toxicity[1].

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
