Sample Buffer is a dilution buffer for specimen and antibodies for direct use in immunoassays.

This buffer is designed for trouble-free assays without interference. The specimen with the analyte, as well as the detection antibody, are diluted in Sample Buffer and then used in the assay.

Sample Buffer is also available without tween or other detergents for use in immunohistochemistry. If you have background or false-positives, such as those from cross reactivities or matrix effects, we recommend you use LowCross-Buffer® rather than Sample Buffer.
