Bis-PEG4-NHS ester is a bis-N-hydroxysuccinimide-activated tetraethylene glycol crosslinker. Bis-PEG4-NHS‘s NHS groups selectively condense with primary amines to form stable amide bonds, thereby covalently crosslinking proteins, peptides, or small molecules. The PEG4 moiety in Bis-PEG4-NHS ester confers good water solubility and flexibility to the conjugate, effectively suppresses nonspecific adsorption, and reduces steric hindrance, thereby supporting site-specific, copper-free click chemistry coupling between antibodies and liposomes. Bis-PEG4-NHS ester can be used for the preparation of homogeneous antibody-drug conjugates (ADCs) and the modular construction of PROTAC bifunctional molecules.

In Vivo Formulation Calculator (Clear solution)

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:
TargetMol | Animal experiments For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, TargetMol | Animal experiments and a total of 10 animals are to be administered, using a formulation of TargetMol | reagent 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH2O , the resulting working solution concentration would be 2 mg/mL.
Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSOTargetMol | reagent 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.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSOTargetMol | reagent stock solution to 400 µL PEG300TargetMol | reagent 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 ddH2OTargetMol | reagent and mix thoroughly until a homogeneous solution is obtained.
