Chloroplast transformation in the green algae Chlamydomonas reinhardtii can be used for the production of valuable recombinant proteins. Here, we describe chloroplast transformation of C. reinhardtii followed by protein detection. Genes of interest integrate stably by homologous recombination into the chloroplast genome following introduction by particle bombardment. Genes are inherited and expressed in lines recovered after selection in the presence of an antibiotic. Recombinant proteins can be detected by conventional techniques like immunoblotting and purified from liquid cultures.
