product information

COXII - mitochondrial cytochrome oxidase subunit II is located in inner mitochondrial membrane. The enzyme is a component of the respiratory chain complex involved in the transfer of electrons from cytochrome c to oxygen.


GST fusion with the aminoacids 4-153 of the subunit 2b of the Chlamydomonas reinhardtii cytochrome oxidase, UniProt: Q9AU05

Host Rabbit
Clonality Polyclonal
Purity Serum
Format Lyophilized
Quantity 50 µl
Reconstitution For reconstitution add 50 ĩl of sterile water.

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

application example

western blot using anti-COXIIb antibodies on Chlamydomonas cell extracts

Chlamydomonas reinhardtii membrane extract (A), Chlamydomonas reinhardtii total cell extract, prepared by sonication, loading 14 µl equivalent to 30 µg of total protein (B), Chlamydomonas reinhardtii total cell extract, rapid, prepared directly by spinning down the cells and lysis of cell pellet in SDS-PAGE sample buffer and loading 14 µl equivalent to 98 µg of total protein (C), denatured at 100°C for 5 min. were separated on 15 % SDS-PAGE and blotted 1h to PVDF using tank transfer. Blots were blocked with 1 % blocking buffer (2 ml blocking reagent stock solution ROCHE 11 520 709 001 in 20 ml TBS) for ON at 4°C without agitation. Blot was incubated in the primary antibody at a dilution of 1: 25 000 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 TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera AS09 602) diluted to 1:20 000 in for 1h at RT with agitation. The blot was washed as above and developed according to manufacture instructions. Exposure time was 8 seconds.
