PsbA | D1 protein of PSII positive control/quantitation standard
The psbA gene has been cloned from many species of plants, green algae, and cyanobacteria. The psbA
GlnA | glutamine synthetase positive control/quantitation standard
The GlnA protein standard can be used in combination with global anti-GlnA antibodies to quantitate GlnA from a wide range of species. Global antibodies are raised against highly conserved amino acid
