H-γ-Glu-Gln-OH (γ-L-glutamyl-L-glutamine) is a highly hydrophilic dipeptide utilized as a building block for advanced drug delivery systems. Carriers composed of H-γ-Glu-Gln-OH, such as poly(L-γ-glutamylglutamine) (PGG), are characterized by high water solubility, superior drug-loading capacity, excellent biocompatibility, and low systemic toxicity. Conjugating drugs (e.g., Paclitaxel) to this peptide moiety significantly improves the solubility of hydrophobic agents and enhances tumor-targeting and tissue penetration (especially in glioblastoma models), leading to optimized anti-tumor efficacy.

DMSO
Note : The dilution table applies only to solid products. For liquid products, please calculate the stock solution based on the stated concentration and/or density. | ||||||||||||||||||||||||||||||||||||
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.
