These particles have a strong affinity for biotin and provide very low non-specific binding since they do not contain any carbohydrates and have a near-neutral isoelectric point (pI) of 6.3. Generally, they are used for diagnostic and molecular biology applicationsDNA/RNA Purification, Antibody/Protein Purification, Cell Isolation, Clinical Diagnosis
