2 µg of total protein from (1) Arabidopsis thaliana WT stressed at 38ºC for 1.5 hour, (2) Arabidopsis thaliana HSP101 null mutant (hot 1-3) were separated on 7.5% SDS-PAGE and blotted 1h to nitrocellulose (Biorad). Blots were incubated in the primary antibody at a dilution of 1: 1 000 for 1h at room temperature with agitation and secondary HRP-conjugated antibody (1: 10 000).

Open PublicationThe expression of HSPs over the period from heat acclimation to the stage of recovery. Ten-day-old seedlings were first acclimated for 2 h at 38 °C, and then exposed to 44 °C for 2 h, and lastly returned to room temperature (RT) for recovery. At the indicated times (shown at the bottom of the picture), proteins were extracted for western blots. ACTIN was used as a loading control.
- Background
-
Background: Hsp101/ClpB is a member of HSP100 protein family. These proteins help protein aggregates formed during heat stress to fall apart to allow them to be refolded by other chaperones. HSP101 is a cytosolic heat shock protein required for acclimation to high temperature.
