Descrição

Descrição geral

As the technology for quantifying chemiluminescence advances, the substrates for chemiluminescence must also advance. For instance, the light emission of conventional enhanced luminol substrates substantially decreases within 30 minutes. In contrast, the chemiluminescence signal of the Lumi-LightPLUS substrate persists for more than nine hours, and since exposures of only a few minutes are necessary, multiple exposures can be taken. Additionally, the ability to take extended exposures allows the detection of rare proteins, or higher dilutions of antigen or antibody to be used. The emission wavelength of the Lumi-LightPLUS substrate is 425 nm.

Comparison of Lumi-Light Substrate and Lumi-Light PLUS Substrate

Lumi-Light Substrate Lumi-Light^PLUS Substrate
Sensitivity 10-50 pg antigen 1-5 pg antigen
Pimary Antibody Dilution Dilute up to 10-fold more compared to colorimetric detection Dilute up to 100-fold more compared to colorimetric detection
Signal Stability >3 hours (enhance signal with a 30-minute incubation) > 9 hours (enhance signal with a 30-minute incubation)

Number of tests: The reagent is sufficient for 10 blots, each with a size of 10 cm x 10 cm.
Sensitivity: Depending on the affinity of the primary antibody, 1 - 5 pg of antigen can be detected in research studies.
Storage/stability: The Lumi-LightPLUS substrate components are stable at +2 to +8°C until the expiration date printed on the label. Components are shipped at +15 to +25°C.

Aplicação

Lumi-Light^PLUS Western Blotting Substrate has been used in western blotting.

Lumi-Light^PLUS Western Blotting Substrate is for the chemiluminescent detection of antigens blotted on membranes using horseradish peroxidase-conjugated secondary antibodies. It can be used for very sensitive detection of any antigen blotted on a PVDF Western Blotting Membrane or nitrocellulose membrane.

Lumi-Light^PLUS Western Blotting Substrate is suited for high-sensitivity western blotting, especially when quantification is required. The chemiluminescent signal persists for more than 9 hours, allowing multiple exposures to be taken.

Características e benefícios

• Detect rare proteins. Detect antigen in the range of 1 - 5 pg.
• Take multiple exposures. The signal is stable for more than nine hours after substrate addition.
• Save sample material. Lumi-Light^PLUS substrate detects less than 5 pg-amounts of antigen.
• Save valuable resources. Dilute primary antibody 10- to 100-fold more than with colorimetric detection systems.
• Benefit from easy preparation. Simply mix the two Lumi-Light components in a 1:1 ratio.

Nota de preparo

Stabilizers: proteinaceous stabilizers
Working concentration: The working concentration of conjugate depends on application and substrate.
The following concentrations should be taken as a guideline:

• Dot blot: 50 mU/ml
• ELISA: 25 mU/ml
• Western blot: 50 mU/ml

Working solution: Preparation of Additional Reagents and Solutions

The table inside the package insert describes the preparation of working solutions. Volumes are designed for a membrane of 10x10 cm. If larger membranes are used, volumes have to be scaled up. For reproducible results, equilibrate all solutions to room temperature before use.
Note: Do not use Azide to stabilize the solutions against microbial growth, as azide irreversibly inhibits horseradish peroxidase.
