high-quality blocking reagent eliminates cross-reactivity

MAXblock™ Blocking Medium is a protein-based, non-mammalian blocking agent for use in immunofluorescence and immunostaining assays. Superior blocking is achieved utilizing a protein blend that demonstrates no cross-reactivity with secondary antibodies. It has been proven effective at blocking non-specific binding of antibodies in immunofluorescence, as well as in immunohistochemistry.

Figure 1: MAXblock blocking efficacy.

Methanol-fixed HeLa cells grown on a coverslip were blocked overnight with MAXblock (A), 5% non-fat dry milk (C), 5% BSA (D) or Thermo-Fisher Pierce Sea Block (E). Cells were then incubated with a fluorescent anti-rabbit secondary antibody at a dilution of 1:250 (far above the recommended dilution to demonstrate the effectiveness of MAXblock), washed with MAXwash and mounted with DAPI. Any observed signal (pseudo-colored red) is caused by non-specific binding of the secondary due to incomplete blocking. Note that no staining is observed in panel A, demonstrating the effectiveness of MAXblock. (Panel B is a 150% overexposure of the fluorescent channel of the MAXblock slide, which shows cell position and demonstrates that antibody binding is barely detectable above background.) Experiments with an anti-mouse secondary gave nearly identical results.
