Streptavidin-PEG2K-cholesterol

Streptavidin-PEG2K-cholesterol/Streptavidin-PEG2000-cholesterol is a versatile bioconjugate.By attaching therapeutics or imaging agents to biotinylated molecules that bind to streptavidin, one can create targeted delivery systems that accumulate in specific tissues or tumor sites, leading to enhanced therapeutic efficacy and reduced side effects.The conjugate can be used to functionalize nanoparticles or liposomes with streptavidin for targeting. Biotinylated drugs or antibodies can be loaded onto these particles for controlled and specific delivery.Utilizing the streptavidin-biotin interaction, this construct can be designed for use in biosensors, where the specificity of streptavidin ensures accurate detection of biotin-labeled targets (e.g. proteins, nucleic acids).Prolonged circulation time due to PEGylation can enhance the effectiveness of streptavidin in various in vivo applications, such as imaging and therapeutic delivery.
