Application examples

Application example

10 ug of a total cell extract of Chlamydomonas reinhardtii: WT _P _HL_High CO2 (1), WT_P_HL (2), Npq4_P _HL (3), were separated on Bolt® 4-12% Bis-Tris Plus Gels (precast) and blotted to PVDF using Bolt® transfer system for 1h . Blots were blocked with 5% BSA/milk for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 for 1h at RT with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and

3 times for 5 min in PBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, AS09 602, Agrisera) diluted to 1:10 000 in for 1h at RT with

agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturer's instructions. Exposure time was 10 seconds.

Background

LHCSR1 (Stress-related chlorophyll a/b binding protein 1) plays a role in an efficient enery dissipation process, called non-photochemical quenching (NPQ), in Chlamydomonas reinhardtii.
