|Washing:||0.1% t-TBS (Product No. 12750)|
|Blocking:||Refer to the figure above|
|1st antibody:||Anti-Vimentin (C-20) (Rabbit) (Product No. SC-7557-R) diluted 1:2,000, 1 hr. at RT|
|2nd antibody:||Anti-Rabbit IgG-HRP (Product No. SC-2004) diluted 1:100,000, 1 hr. at RT|

PVDF membranes dot-blotted with mouse serum were washed with TBS. Blocking was performed using each reagent above. Anti-mouse IgG (Cat.#SC-2005) (1:5,000 in 0.01% t-TBS) was applied, and the membranes were washed with 0.05% t-TBS. After reaction with Chemi-Lumi One Super (Cat.#02230), detection was performed using LAS-3000 (High mode) with 90 sec. exposure time.
Diluting antibody with Bullet Blocking One resulted in less non-specific binding compared to using t-TBS as diluent.

|1st antibody:||Anti-Cox4 (D-20) (Goat) (Product No. SC-69359) diluted 1:500, 1 hr. at RT|
|2nd antibody:||Anti-Goat IgG-HRP (Product No. SC-2350) diluted 1:5,000, 1 hr. at RT|
|Detection:||Chemi-Lumi One Super (Product No. 02230), 1 min. reaction time|
|Detector:||LAS-3000 (High mode), 10 min. exposure time|
For antibody dilution, use Bullet Blocking One undiluted, or dilute up to 20x with TBS or PBS containing 0.05 – 0.1% detergent, such as Tween 20. The appropriate dilution ratio depends on antibody conditions, such as type and concentration, pretest is required.
Bullet Blocking One showed good blocking efficiency in 5 min. Although optimizations of dilution ratio to types of antibody are required beforehand, in this experiment, diluting the antibody with Bullet Blocking One resulted in the strongest signal.
