Chemoluminescence was recorded by Image Station 4000MM (Kodak) and intensities of bands were measured by using Image J 1.37v (NIH, USA).
Finally, detection of specific proteins was performed by enhanced chemoluminescence reagent (Western Lightning ECL Pro, Perkin Elmer).
The signals were developed with the chemoluminescence luminal reagent (Santa Cruz Biotechnology) according to the protocol.
Chemoluminescence was measured using the ChemiDoc MP Imaging System (BioRad).
Nitrocellulose paper (BA85, 0.2 [micro]m) and the reagents for chemoluminescence protein labeling in immunoblots were purchased from Amersham (Aylesbury, UK).

Samples were incubated and washed again and the chemoluminescence initiating mixture was added.
The distinction from the mostly blue (and UV) chemoluminescence of a homogeneous pre-mixed flame is unambiguous.
After the membrane was washed, the immunoreactive bands were visualized by enhanced chemoluminescence with a camera-based imaging system (Alpha Innotech, Santa Clara, CA, USA).
