Using a standard Amicon® Ultra centrifugal filter, a few rounds of diafiltration can efficiently remove unincorporated label from an antibody labeling reaction without diluting the sample.
PKH dyes have been successfully used to label exosomes and extracellular vesicles for in vitro and in vivo tracking experiments. The exosome labeling protocol below details steps for reliable fluorescent labeling of exosomes using PKH dyes for microvesicle tracking experiments.
This page shows coupling through the primary amine of a ligand with a NHS-activated Sepharose High Performance, NHS-activated Sepharose 4 Fast Flow and CNBr-activated Sepharose from Cytiva.
The development of modern mass spectrometry (MS) equipment with high resolution and mass accuracy has led to its use in analyzing glycans for both profiling and structural studies.
Enzymatic Deglycosylation Strategies: Sequential hydrolysis of individual monosaccharides from glycans can be useful for the elucidation of the structure and function of the glycan component.
CIP is used to remove 5’-phosphate groups from DNA, RNA and both ribo and deoxy-ribonucleoside triphosphates. Detailed protocol on how to dephosphorylate DNA.
