dos.5. California dos+ imaging for the neonatal OHCs The latest rodent Ocm gene (series during the Contour S01) are cloned on the pcDNA3.1CFP and you will pEGFP-N1 Flag (Addgene #60360). Following, EGFP-Flag are got rid of playing with BamHI (NEB) and NotI (NEB) and substituted for the newest mCherry sequence (gene cut-off out of mCherry out of Qiagen) to manufacture pOcm-mCh. Rodent Apv and Sri (custom ordered gene cut off of IDT, Coralville, IA) (sequences within the Figure S01) was basically swapped to the Ocm web site playing with HindIII (NEB)/BamHI or HindIII/SalI which will make pApv-mCh and you may pSri-mCh, respectively. The latest mCherry plasmid as well as substitute new Banner linker with a flexible GS linker (SGGGGSGGGGSGGGGS) between Ocm/Apv/Sri and mCherry. New mCh control plasmid try created by cloning from Ocm gene away from Ocm-mCherry. Nucleotide sequences to possess rodent Ocm/Apv/Sri and you will plasmid sequences to possess pOcm-CFP, pmCh, pOcm-mCh, pApv-mCh and pSri-mCh can be found in Shape S01.

Human Embryonic Kidney (HEK293T) cells were maintained in Dulbecco’s Modified Eagle Medium (DMEM, Thermo Fisher) supplemented with 10% fetal bovine serum (FBS, Bio-techne) at 37 ? C in a 5% CO2 incubator. Transfections were performed using Lipofectamine 3000 (Thermo Fisher Scientific) in Opti-Mem reduced serum media (Thermo Fisher) according to manufacturer’s protocol. Mammalian cells were transfected with either mCherry (mCh), Apv-mCh, Ocm-mCh, Sri-mCh, or Ocm-CFP plasmids. 24 hours post transfection, growth media was replaced with HBSS (Gibco) before Ca 2+ transient experiments.

OHCs from CBA/CaH Ocm +/ – and Ocm – /- mice of both sexes were acutely dissected at P2 and P3. (more…)
