Observe your pre-stained marker in ECL experiments：
After chemiluminescent development, the position of the pre-stained marker drawn by LuminolPen can be visualized and recorded for further evaluations. Molecular weight of the target proteins can be easily estimated. Download our brochure.

Quality control (QC) your chemiluminescent substrate :
LuminolPen can be taken as an internal control to ensure the chemiluminescent substrate you use is still functional. Signals from the area marked by LuminolPen indicate that the chemiluminescent substrate is functional.

Take notes where necessary：
You can use LuminolPen to make your experimental notes on the transferred membrane. The blue ink allows researchers to easily mark
(1) the size of pre-stained marker,
(2) the lane numbers
(3) other important experimental parameters.

Storage Conditions
Stable for 1 year at 4°C.
Do not freeze

Please Note
During ECL it is important to use the correct blocking agent. The high MW of casein may block the signal labeled by 2nd antibody, so you have to use higher concentration of antibody to get the better signal. Skimed milk also contains too much high MW protein that may effect the result. We suggest that you try Gelatin or BSA as blocking solution to acheive the best results.
