Hypersensitive ECL Chemiluminescence Kit
-Femtogram-

luminol ECL chemiluminescence에 기반한 ECL solution입니다.
본 제품은 2차항체에 붙어있는 horseradish peroxidase (HRP) 에 반응하여,  형광을 발생시킵니다. X-ray 방식이나 Chemiluminecence Imaging (doument) System을 이용해 검출이 가능합니다. 매우 낮은 농도의 샘플도 검출해 낼 수 있으며, 샘플을 절약할 수 있습니다. 적은양의 항체를 사용하여 인큐베이션 시킨 샘플의 신호도 잡아 낼수 있으며, 이렇게 항체를 절약할 수도 있습니다. Sensitive ECL Chemiluminescence Kit (G2074)와 비교해서 10배이상의 높은 감도를 나타냅니다.

Product Description/Introduction

ECL chemiluminescence Kit is a highly sensitive chemiluminescence kit based on luminol ECL chemiluminescence. This product can react with horseradish peroxidase (HRP) conjugated on secondary antibody to produce fluorescence and detect samples by using X-ray lithography or other appropriate fluorescence imaging equipment (fluorescence or chemiluminescence imaging system, etc.). Low concentration samples can still be detected, saving samples. Signal can still be detected after incubation with low concentrations of antibodies (primary, secondary), saving precious antibodies. Signal values are enhanced at least 10-fold compared to the Sensitive ECL Chemiluminescence Kit (G2074).

Storage and Shipping Conditions

Ship with wet ice; Store in the dark at 2-8℃, valid for 12 months.

Assay Protocol/Procedures

1. hypersensitive ECL working solution 준비: the hypersensitive ECL solution A와 hypersensitive ECL solution B  같은 볼륨으로 섞음. 해당 솔루션은 실온에서 바로 사용 가능합니다.

2. Western 실험에서, PVDF membrane (또는 NC membrane)는 2nd Ab 반응 시키고, 몇 번의 washing과정을 거친 후에,  위에서 섞은 ECL working solution이 membrane을 덮을 정도로 넣은 후 1~2분간 반응 시킵니다.

3.  ECL working liquid를 filter paper나 absorbent paper로 흡수 시켜 제거하거나, membrane을 꺼내서 촬영을 위한 비닐 판 또는 보드판에 놓아 줍니다.

4.  pressed film에 사용한다면 develop과 fixed과정을 거칩니다.(G2019, G2023, G2024추천합니다.). 촬영을 합니다.

Note

1. Be sure to change the pipette tips during pipetting of Reagent A and B to avoid cross-contamination, which may result in the failure of active components.

2. Please wear gloves and use clean equipment such as tweezers to avoid contamination by exogenous proteins and metal ions during contact with the membrane.

3. Sodium azide inhibits HRP activity and all related reagents should be avoided.

4. Please use up the ECL working solution within one day after it has been configured, do not leave it until the next day, so as not to affect the accuracy of the experimental results.

5. After the use of each solution, please keep the bottle tightly capped and keep it away from light to prevent failure; especially solution B, which contains oxidizing agents and is easily reduced and become ineffective. In addition, liquid A should not be stored close to the inner wall of the refrigerator to prevent the precipitation of crystals due to the local temperature is too low. If crystals are precipitated, dissolve and mix in 37℃ warm water bath before use.

6. ECL chemiluminescence reagent kit selection refer to Table 1, primary antibody and secondary antibody recommended dilution ratio test data are from self-research antibody.

7. Refer to Table 2 for common problems and solutions for ECL chemiluminescent assays.

8. ECL chemiluminescence kit A/B solution are harmful to human body, must be careful when handling, pay attention to effective protection, avoid direct contact with the human body or inhalation of the respiratory tract.

9. For your safety and health, please wear safety glasses, gloves, or protective clothing.

Table2:Common problems and Solutions of ECL Chemiluminescence Detection

Common Problems

Possible Causes

Solutions

High background (high background or no specific bands)

Primary and secondary antibody dilution without using the correct buffer and concentration

Appropriately reduce the dilution ratio, reduce the concentration of primary and secondary antibodies

Blocking time or washing time is too short, or blocking solution is incorrect

Phosphorylated protein assays should always be closed with BSA or protein-free closures; the smaller the membrane pore size, the longer the closure and elution time should be

Inadequate incubation of primary antibody

Appropriately prolonged incubation time (overnight incubation at 4°C)

Weak or No Signal

Low concentration of primary and secondary antibodies used

Increase the concentration of primary and secondary antibodies used

Low protein abundance

Increase sample volume

Switching to a more sensitive ECL chemiluminescence kit

Rapid fluorescence burst, hollow bands (ghost bands) appear

The fluorescence of the target band is too strong, which rapidly consumes the luminescent substrate, and after the substrate is consumed, it will be anti-white.

Reduce the amount of protein uploaded or the amount of primary and secondary antibodies

Brown or yellow bands appear on the membrane

Over-abundance of HRP in the target region generates large amounts of free radicals, resulting in oxidative inactivation of HRP

Reduce the amount of protein uploaded or the amount of primary and secondary antibodies
