WebbAn IgG subclass with 1-2 pluses will bind at 1-5 mg IgG per mL resin. A subclass with 3-4 pluses will bind at 10-25 mg per mL resin. Protein L is able to bind all Ig classes and can bind 3-10 mg Ig per mL resin for species with 4 pluses. It is recommended that the resin to be used have at least 2 pluses for the species and Ig class of the ... Protein A is often coupled to other molecules such as a fluorescent dye, enzymes, biotin, colloidal gold or radioactive iodine without affecting the antibody binding site. Examples including protein A–gold (PAG) stain is used in immunogold labelling, fluorophore coupled protein A for immunofluorescence, and DNA docking strand coupled protein A for DNA-PAINT imaging. It is also widely utilized coupled to magnetic, latex and agarose beads.
