Generating a Battery of Monoclonal Antibodies Against Firefly Luciferase for Dot Blot Analysis, Western Blot Analysis, and Immunostaining of Cells in Culture and Paraffin Sections

Monoclon Antib Immunodiagn Immunother. 2018 Feb;37(1):45-51. doi: 10.1089/mab.2017.0057.

Abstract

Firefly luciferase (FLuc) is commonly used as a reporter gene PpyLuc1 in bioanalytical assays. We have produced five mouse-derived monoclonal antibodies (mAbs) that recognize FLuc. The mAbs, DSHB-LUC-2, DSHB-LUC-3, DSHB-LUC-9, DSHB-LUC-16, and DSHB-LUC-24, were generated by immunizing mice with purified 6xHIS-tagged FLuc (6xHis-FLuc) in suspension with an adjuvant. All five were validated by dot blots. Four of the mAbs provided strong signals in western blot analysis, and one a weak signal. All five were validated for immunostaining in fixed cell culture. Only one stained cells embedded in paraffin. The five mAbs are available at cost through the Developmental Studies Hybridoma Bank (DSHB), a nonprofit National Resource created by the National Institutes of Health.

Keywords: firefly luciferase; immunofluorescence; paraffin; western blot.
