GO-Blot™ V2: Fully Automated and Programmable Western Blot Processor

$0.00

NEW GO-BlotV2

A Western blotting device has never been so flexible and easy to use as the new GO-Blot™ V2. There are three tray sizes to choose from and infinite (nearly) combinations of Protocols to create. In addition, there is a growing community of users that share their successful protocol/antibody combinations on the Global Western Portal™.

The GO-Blot V2 Western Blot Processor is a reliable fluid delivery device for reproducibly probing blots and membranes with primary and secondary antibodies. It was developed after communication with hundreds of research scientists over the past two years. They required a cost-effective machine that would reproduce the hands-on method using a rocker platform and exchanging buffers manually.  Click here to see the GO-Blot V2 in action.

The equipment is composed of valves, pumps, a motorized tilting platform and a control board that coordinates timing with the application of the correct solution to the membrane or blot. It can operate at room temperature or in a cold room*. All commonly used buffers are applicable, e.g. PBST and TBST. The purchase of the machine comes with a full warranty (parts & labor or replacement) for up to one year after the date of purchase. 

* - Note cold room operation on order if applicable.


GO-Blot V2 Advantages

No Expensive Consumables and Recycles Your Primary Antibody

The GO-Blot V2 allows the operator to load their own membranes and add their blocking solution, primary and secondary antibodies to reservoirs.  The machine handles the rest of the western blot processing.  Plus, the GO-Blot V2 makes it easy to recycle your primary antibody.

Modular and Economical

The machine is designed to be modular and economical so that you utilize multiple machines running at different times with different routines and different antibodies, in other words, it’s very flexible for multiple users. Also being modular means that you can add new units when the budget allows or your project demands it.

Create your own routines

You can program your own runs through the easy to use mygoblot.com website through your phone and share them with users around the world using the globabl western portal. Labs which require more secure options are not required to share their runs or results. 

 

Applying liquids to the processor

It is important to pour and pipette accurately into the Wash, Primary and Secondary reservoirs because liquid overflows can result in equipment malfunction. To ensure good technique pour Wash buffer into the middle of the Wash Buffer reservoir, and for the syringe loading technique use a pipettor to pipette into the syringe at a depth that is below the rim.

 

Blocking solution

The most generally applicable blocking solution is TBST with 5% (w/v) dried milk powder. However other blocking reagents are possible such as 1% BSA or 1% non-specific IgG. TBST is Tris buffered saline with Tween 20 which contains 10 mM Tris-HCl pH 7.0, 150 mM NaCl and 0.05% (v/v) Tween 20.

 

Primary antibody volume 

The best volume of primary antibody is 10 ml, at this volume all routines run efficiently and will not be subject to the effects of evaporation. 

Dilute primary antibody in TBST or if this concentration produces high background then use TBST with 1% milk.

 

Cold room operation

The GO-Blot™ V2 can be operated in a cold room at 4°C, but it is not recommended to move the machine to room temperature in the middle of a routine because if the  power is disconnected the program will need to be re-started from the beginning, hence routines should be run at one temperature.

 

Secondary antibody solution

The secondary antibody is raised to the primary IgG species and usually is conjugated to horse-radish peroxidase (HRP) or alkaline phosphatase (AP).Dilute secondary antibody 1:20,000 in TBST or if this concentration produces high background then use TBST with 1% milk.

 

The device is used by Cytoskeleton Inc. research and development scientists to characterize and validate the new line of antibodies.

Q1. How do I connect to my phone?

A1:

This connection method is the most simple and direct, it allows the user to quickly access the programming and protocol tracking functions from a mobile phone.

1. Click the “Down” button on the front panel to Connectivity.
2. Click “Enter” button.
3. Scan the QR code with your phone's camera.
4. Choose GO-Blot V2 Wifi connection from your phone’s Settings>Wifi location. Make sure this is connected by seeing the check (tick) mark.
5. Go to the phone’s browser, and type in 10.1.1.1 and hit Enter or GO.
6. A green page with the GO-Blot V2 menu in green will pop up.
7. Tap Create Protocol to start programming the steps for your unique Western Protocol.

Q2. How do I create a protocol?

A2:

Continue from A1 above, or open a browser in a computer or phone.
Type in the IP address of the GO-Blot V2 into the address bar and tap Enter or Go respectively.
1. Tap on “Create Protocol” 
2. Fill out each field with appropriate data, (e.g. the wash steps have two data points, the first one is number of washes, the second is length of each wash in minutes.)
3. When it is complete, tap “Submit” to save the new Protocol.


Note: New Protocols are listed chronologically, therefore the latest protocol will be at the end of the list.
Note: The Large tray type will be limited automatically if there are too many washes, the maximum number of washes for the Large tray Is 12 total.
Tip: If you cannot see the Submit button on the iphone version, shrink the screen and/or tap on AA symbol in the address bar, and chose “Hide address bar” option.
Tip: Pause buttons are useful to pause the run while adding a labile reagent or checking a routine’s timing.

 

Q3. How do I run a protocol?

A3:

Warning: do not load solutions until the Water Wash Protocol has run.


A Water Wash is necessary to start using your GO-Blot V2 and to ensure all systems are working well. A Water Wash is also recommended after greater than 1 week without a run. Sometimes the last operator might forget to clean the machine with a Water Wash, in this situation the Water Wash must be run before using the machine.


1. While standing next to the GO-Blot V2 check that no solutions are in any reservoirs or trays.
2. Connect the luer locks with tubing to the front of the machine.
3. Place the left and right-side tubing into a waste container.
4. While on the Main Menu, scroll down by clicking the machine’s “Down” button until you reach the Run Protocols line.
5. Click the “Enter” button.
6. Scroll down to highlight the Water Wash, and click Enter.
7. An alert should pop-up indicating to fill the Water Wash reservoir, lets do this by adding 425 ml to the container which covers the level sensor.
8. The alert should disappear and the option to Run the protocol appears, click Enter to run the protocol.


Note: The same approach is used to run a protocol, except you need to add Blocking solution and membrane to the tray, TBST (or PBST) to the Buffer reservoir and appropriate Primary and Secondary antibody solutions to their respective receptacles. Also, place the right-side “Recycle” tubing into a clean recycle vessel (e.g. 15 or 50 ml disposable tube). Then chose a protocol from the list. Pre-defined Protocols are at the top of the list and User defined (with a “U” before the number) ones at the end of the list.

Warning: Be sure to visit the machine and view the screen before adding antibody and buffer solutions. If a previous operator did not run the Water Wash, then it will be required before continuing, an alert will be visible, any buffers and antibody solutions loaded at this point will be washed away!

Note: If there is a sticky-high affinity antibody left over from a previous run. The best way to clean the device is to add 50 ml of either 1 x SDS-running buffer from a PAGE system (e.g. a standard composition is 50 mM Tris-HCl pH 6.8, 100 mM NaCl, 0.1% SDS) to all the reservoirs. Then choose the Water Wash protocol to run the solution through the system. Then follow with two Water Washes using pure water only.
