Tetra(-amido-PEG23-MAL) pentaerythritol is a special branched PEG linker with terminal maleimide groups that react with thiols between pH 6.5 to 7.5. The lengthy PEG chains elevate hydrophilicity and help with fine-tuning DMPK properties. Branched linkers allow for more payload attachment to ADC. Please contact us for GMP-grade inquiries.
