IgG fraction Monoclonal Mouse Anti-Biotin may be used either as direct conjugates, or for more sensitivity, they can be used unconjugated followed by a conjugated anti-mouse IgG (H+L) for signal enhancement.
40 nm Colloidal Gold
Colloidal gold conjugates are widely used commercially in lateral flow immunoassays due to their ease of production, conjugate stability and intense optical properties that generate highly sensitive tests with results visible to the naked eye.Conjugates are prepared by passive absorption of the antibody to the gold particle, and are sterile filtered in a low ionic strength buffer containing a preservative.
