One-Step Western^TM Multiplex Kit II (β-Actin), Mouse

Description:

Western blot analysis is one of the most common methods of detecting proteins and of determining specific protein concentrations in biological samples. However, loading errors and other human problems can confound this otherwise reliable system. An internal control is often needed to control and correct for such problems and to semi-quantitate protein expression levels. To date, the three most widely used internal controls are housekeeping proteins GAPDH, β-actin, and α-tubulin. However, to avoid crossover reactions, researchers usually need to perform two Western blots, either by cutting the membrane into half or by stripping the membrane after the first blot, to detect the target protein and the internal control separately. GenScript One-Step Western^TM Multiplex Kit II can detect both the target protein and β-actin in a single blot on the same membrane. Like other kits employing GenScript's One-Step Western^TM technology, it cuts blot time down to about one hour.

Using GenScript's immunodetection technology (patent pending), the kit replaces the classical three-step Western, which can take nearly five hours. To use the One-Step Western^TM Multiplex Kit II transfer the proteins from gel to membrane and incubate it in the pretreat solution for five minutes. Then incubate in WB solution with primary antibody for 40 minutes, and, lastly, wash three times for ten minutes each. The membrane can then be developed with the HRP substrate included in the kit. The kit contains all the necessary reagents, buffers, nitrocellulose membrane, and HRP substrate for performing a Western blot.

The One-Step Western^TM Multiplex procedure is contrasted with a classical three-step Western at right. The One-Step Western^TM Multiplex Kit II already contains a β-actin antibody that specifically reacts with human, mouse, rabbit, chicken, hamster, cow, goat, fish, and pig β-actin protein. This kit requires only a primary antibody for the target protein.

The One-Step Western^TM Multiplex Kit II contains WestClear^TM Nitrocellulose Membrane (0.2 µm) and LumiSensor^TM Plus Chemiluminescent HRP substrate optimized for best results. WestClear^TM Nitrocellulose Membrane and LumiSensor^TM Plus Chemiluminescent HRP Substrate Kits are also available separately.

Key Features:

Easy to perform: This kit has fewer and simpler steps than other Western kits, leaving fewer chances for human error.

Low background: The kit contains WestClear^TM Nitrocellulose Membrane and LumiSensor^TM Plus Chemiluminescent HRP Substrate Kit, optimized for low background.

High sensitivity: The kit's sensitivity is comparable to or better than that of the classical 4.5-hour procedure, depending on the quality and amount of antibodies used.

Reproducible results: The kit produces highly reproducible results.

No additional secondary antibody is needed: No extra β-actin antibody is needed.

The One-Step Western^TM needs far less optimization than the classical three-step method.

Shown below is a One-Step WesternTM Multiplex Blot performed using rabbit polyclonal antibody. The One-Step WesternTM Multiplex Kit II (β-Actin), Rabbit (GenScript, L00318) was used to detect both β-actin and GST protein (with the MW of about 26 kDa) in Hela cell lysate spiked with GST protein.
