mPEG-amine (mPEG-NH2) (MW 5000) is a modifier that can replace the sulfonic acid portion of dye molecules to enhance the water solubility of long-wavelength voltage-sensitive dyes (VSD) or Pittsburgh (PGH) dyes. It also forms amide bonds with carboxyl groups on microsphere surfaces in the presence of EDC and Sulfo-NHS, creating a PEG coating on fluorescent microspheres for large-scale rotational cytoplasmic flow studies.

Dissolve 2 mg of the compound in 100 μL DMSO
to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.
1) Add 100 μL of the DMSO
stock solution to 400 μL PEG300
and mix thoroughly until the solution becomes clear.
2) Add 50 μL Tween 80 and mix well until fully clarified.
3) Add 450 μL Saline,PBS or ddH2O
and mix thoroughly until a homogeneous solution is obtained.
