BS054: Magnetic Bead Conjugation Service
Highly efficient process to conjugate magnetic beads to clients' peptides, proteins, and antibodies: the ratio is 20 ug protein or antibody per mg magnetic microbeads in the conjugation reaction; about 6 ug protein or antibody would be conjugated onto the beads at a concentration of 6 ug antibody per mg magnetic beads.
