体外研究

Congo Red histochemical stain may serve as a simple screening tool for investigating if the aggregates in mutant cells have misfolded β-pleated sheet secondary structures.Congo Red histochemical dye has the ability to bind specifically to crossed β-pleated sheet structures.Wild-type HSPB1 should maintain protein homeostasis by binding proteins in non-native conformations,thereby preventing substrate aggregation.The T139M mutant, however, fails in this function and results in an accumulation of misfolded proteins,which are targeted by Congo Red for intercalating between the β-pleated sheet structures. Congo Red histochemical stain may serve as a simple tool to investigate if the aggregates in mutant cells have misfolded β-pleated sheet secondary structures.

 

推荐实验方法(仅供参考)

细胞实验:

 

HeLa cells are selected for these studies due to their large cytoplasmic volume.Cells transfected with mutant or wild-type HSPB1 constructs are grown on coverslips for 24hr and then are stained with Congo red to determine if the aggregates display amyloidogenic properties.Briefly,cells are first fixed with 10% formalin for 10 min and stained with 1% Congo red for 5 min,followed by destaining with 0.01% potassium hydroxide in 50% ethanol.Coverslips are then passed through graded ethanol concentrations for dehydration and mounted in a mounting medium and examined by fluorescent microscopy under rhodamine filter.
