Description

Excellent Chemiluminescent Substrate is an enhanced chemiluminescent (ECL) substrate for horseradish

peroxidase (HRP) enzyme that provides low picogram detection of proteins in Western blot and ELISA

applications.

Excellent Chemiluminescent Substrate emits light for longer and chemiluminescent signal at more than

twice the intensity of other entry-level luminol-based horseradish peroxidase detection systems while

also maintaining sensitivity and low background. In addition, the range of the calibration curve is much

wider than other competitors. Also, the greater signal intensity is achieved using less primary and

secondary antibody than typical ECL substrates. All of this for about 30% less cost than comparable

products.

ECL substrate – An enhanced chemiluminescent substrate for detection of horseradish

peroxidase (HRP) activity of antibodies and other ELISA or Western blot probes.

Economy – Costs less per milliliter than other similarly sensitive chemiluminescent substrates.

Picogram sensitivity – Highly sensitive for the rapid development of a wide range of protein

levels.

Stable light output – Long-duration signal makes it possible to make multiple exposures to film.

High intensity – Signal is twice as strong as output from other luminol-based systems.

Excellent stability – 8-hour working solution stability; 1-year kit stability at 2~8℃.

Saves antibody – Requires much less (more dilute) primary and secondary antibodies per blot.

Wide range of the calibration curve –Calibration curves range from 4.00–8000 pg, R2 is 0.992.

Detailed Western Blotting Procedure

1. Remove the blot from the transfer apparatus and block nonspecific sites with Blocking Reagent

for 20-60 minutes at room temperature (RT) with shaking. For best results, block for 1 hour at RT.

Note: Avoid using milk as a blocking reagent when using Avidin/Biotin systems because

milk contains variable amounts of endogenous biotin.

2. Remove the Blocking Reagent and add the appropriate primary antibody dilution. Incubate the blot

for 1 hour with shaking. If desired, blots may be incubated with primary antibody overnight at 2-

8°C.

3. Wash the membrane by suspending it in Wash Buffer and agitating for ≥ 5 minutes. Replace Wash

Buffer at least 4-6 times. Increasing the wash buffer volume and/or the number of washes may help

reducing background.

Note: Briefly rinsing membrane in wash buffer before incubation will increase wash

efficiency.

4. Incubate the blot with the appropriate HRP-conjugate dilution for 1 hour at RT with shaking.

5. Repeat Step 3 to remove non-bound HRP-conjugate.

Note: Membrane must be thoroughly washed after incubation with the HRP-conjugate.

6. Prepare Working Solution by mixing equal parts of the Substrate A and Substrate B. Use 0.1 mL

Working Solution per cm

of membrane. The Working Solution is stable for 8 hours at RT.

Note: Exposure to the sun or any other intense light can harm the Working Solution. For

best results keep the Working Solution in an amber bottle and avoid prolonged exposure to

any intense light. Typical laboratory lighting will not harm the Working Solution.

7. Incubate the blot with Working Solution for 5 minutes.

8. Remove the blot from Working Solution and place it in a plastic membrane protector, a plastic

sheet protector or plastic wrap may be used. Use an absorbent apparatus to remove excess liquid

and to carefully press out any bubbles between the blot and surface of the membrane protector.

9. Place the protected membrane in a film cassette with the protein side facing up. Turn off all lights

except those appropriate for film exposure (e.g., a red safelight).

Note: Film must remain dry during exposure. For optimal results, perform the following

precautions:

• Make sure excess substrate is removed from the membrane and the membrane protector.

• Use gloves during the entire film-handling process.

• Never place a blot on developed film, as there may be chemicals on the film that will reduce

signal.

10. Carefully place a piece of film on top of the membrane. A recommended first exposure time is 60

seconds. Exposure time may be varied to achieve optimal results. Enhanced or pre-flashed film is

unnecessary.

Note: The exposure time may be varied to achieve optimal results. If the signal is too intense,

reduce exposure time or optimize the system by decreasing the antigen and/or antibody

concentrations.

Light emission is most intense during the first 5-30 minutes after substrate incubation. Light

emission will continue for several hours, but will decrease with time. Longer exposure times

may be necessary as the blot ages.

Attention: Light emission is intense and any movement between the film and membrane may

cause artifacts on the film.
