Fig. 7From: A cell death assay in barley and wheat protoplasts for identification and validation of matching pathogen AVR effector and plant NLR immune receptorsOverview of steps for the adjustment of protoplast density and preparation of plasmid for transfection. Step 12: 0.5 ml of Wash Buffer containing protoplasts is transferred to cuvette. Step 13: Round bottom tube containing isolated protoplasts in Wash Buffer is placed in dark environment to let protoplasts settle for 45 min. Step 14: Protoplast concentration is determined. Step 15: Preparation of plasmid transfection mixtures. Step 16: Wash Buffer is removed from protoplast pellet using a pipette. Step 17: Transfection Buffer 1 is added to protoplast pellet for a calculated final OD600 = 0.4Back to article page
