Propidium Iodide (solution)	Fluorescent Dye DNA/RNA Synthesis	Others
Propidium Iodide (PI) (solution) is a nuclear staining agent that stains DNA. Propidium Iodide is an analogue of ethidine bromide that emits red fluorescence upon embedding in double-stranded DNA. Propidium Iodide cannot pass through living cell membranes, but it can pass through damaged cell membranes to stain the nucleus. Propidium Iodide has a fluorescence wavelength of 493/617 nm and a wavelength of 536/635 nm after Mosaic with DNA. Propidium Iodide is commonly used in the detection of apoptosis (apoptosis) or necrosis (necrosis) , and is often used in flow cytometry analysis. Solvent and Concentration: Sterile water: 1 mg/mL The 1 mL volume is defined as the base specification. All larger sizes correspond to incremental volumes of this base.

HY-DY1036

Calcein-AM (solution)	Fluorescent Dye	Cancer
Calcein AM (solution) , has cell membrane permeability and can easily enter the cell. Calcein AM has no fluorescence and is hydrolyzed by endogenous esterase in the cell to produce polar molecule Calcein (Calcein) , which has strong negative charge and cannot permeate the cell membrane. Calcein can emit strong green fluorescence, so it is often used with Propidium Iodide for cell viability/virulence detection, excitation/emission wavelength: 494/515 nm . Solvent and concentration: DMSO: 2 mM

Western blot analysis of extracts from THP-1(lane 2(20μg), Jurkat (lane 3(20μg) and NIH3T3(lane 4(20μg) using FOXO1A (HY-P80132) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
