4arm-PEG20k-TK-NHS

The compound 4arm-PEG2k/20k-TK-NHS consists of a 4-arm polyethylene glycol (PEG) polymer with molecular weights of 2k (2,000 daltons) and 20k (20,000 daltons) attached to a thymidine kinase (TK) group through an N-hydroxysuccinimide (NHS) ester linkage.

This compound is often used in bioconjugation and drug delivery applications. The PEG arms provide water solubility and can help improve the pharmacokinetics and biodistribution of the attached molecule. Thymidine kinase (TK) is an enzyme that can be utilized in prodrug therapy, where the enzyme can convert a prodrug into its active form selectively in cells expressing TK, such as cancer cells.

We can mass produce (kg level),process scaling up, pilot supply,raw material supply, and intermediate production. Our production technology is mature and more cost-effective. Feel free to inquire at any time.
