AsurDx™ ELISA Blocking Buffers

Biostone Animal Health  AsurDxTM blocking buffers can block excess binding sites in ELISA. These blocking buffers reduce or eliminate many of the problems encountered with traditional blocking reagents, such as cross-reactivity and interference from glycosylation. Additionally, AsurDxTM blocking buffers are compatible with antibodies and avidin/biotin systems. Some of the blocking buffers contain  the detergent Tween 20, which improves blocking performance in many detection systems.

*Warning: Read the Safety Data Sheets (SDSs) and follow the handling instructions. Wear appropriate protective eyewear, clothing, and gloves.  For Research Use Only. Not for use in diagnostic procedures.

Block ELISA Plates

1.Coat the ELISA plate with antigen or antibody.

2.Add 300 µL of AsurDxTM blocking buffers to each well, then incubate the plate for 1 hour at room temperature or 37°C. Alternatively, add 300 μL of blocking buffer to each well, then immediately invert the plate to empty contents. Repeat this process two more times.

3.Proceed with the ELISA protocol that is appropriate for your downstream detection. For storage, invert plate for approximately 2 hours to dry. Transfer plate to a plastic bag or other container containing a desiccant, such as silica gel. Store the plate at 4°C.
