LodeStars 2.7 Carboxyl are superparamagnetic particles that are nominally 2.7 μm in diameter and have a surface covered with carboxylic acid groups. The carboxylic acid groups can be covalently coupled to ligands, which allows the particles to be used to identify and isolate targets in biological samples.
Agilent LodeStars 2.7 Carboxyl are superparamagnetic particles with a diameter of 2.7 um, designed for use as a solid phase in manual and automated assays. The particles feature a polymer shell with carboxylic acid groups for covalent coupling of ligands such as antibodies, antigens, and enzymes. They are supplied as a suspension in phosphate buffered saline (PBS) and are stable over a wide pH range.
