Source: Creative Biolabs
Description
Creative Biolabs provides custom oligonucleotide-aptamer conjugation services to facilitate targeted drug delivery, molecular diagnostics, and gene therapy applications. The service couples therapeutic or diagnostic oligonucleotides—such as siRNA, miRNA, shRNA, and ASOs—to targeting DNA, RNA, or chemically modified aptamers via bifunctional linkers. Production utilizes automated solid-phase phosphoramidite chemistry followed by HPLC and FPLC purification. Comprehensive analytical quality control includes mass spectrometry, gel electrophoresis, UV-Vis spectrophotometry, target binding assays, and cellular uptake studies.
Best for
Gene therapy researchers, Biomedical scientists, Developing targeted oligonucleotide drug delivery systems and Enhancing precision and reducing off-target effects of RNA therapeutics

Description
Beadlite Rapid Colorimetric Thiol Quantitation Kit for Nanoparticles by AAT Bioquest is an assay kit designed to quantify free sulfhydryl and thiol groups on thiol-functionalized nanoparticle surfaces. Utilizing proprietary Thiolite 490 with maximum absorbance at 490 nm, the kit measures unreacted dye after excess reaction to determine surface thiol density. Compatible with latex beads, agarose beads, and magnetic nanoparticles, it supports readouts on standard cuvettes, NanoDrop spectrophotometers, and 96-well microplate readers.
Best for
nanotechnology researchers, bioconjugation scientists, quantifying surface sulfhydryl groups on nanoparticles and characterizing thiol-functionalized latex, agarose, or magnetic beads
