To avoid a hardware crash and equipment damage, ensure that the wash station contains the white wide-bore chimneys when using the 25 µL cartridges. Note: The white wide-bore chimneys work for both 5-µL and 25-µL cartridges and are standard on wash stations purchased in 2020 onward. The wide-bore chimneys are white plastic, whereas the standard-bore chimneys are a semi-clear plastic. For details, see the 96 Channel Wash Station Maintenance Guide.
Optional equipment. The following equipment is recommended when preparing the samples and reagents:
• Microplate centrifuge, such as the Agilent Microplate Centrifuge or equivalent
• Microplate sealer, such as the Agilent PlateLoc Thermal Microplate Sealer or equivalent

AssayMAP cartridges
The following table lists the available AssayMAP cartridges for performing Affinity Purification on the AssayMAP Bravo Platform. Each cartridge type can be purchased as a rack of 96 cartridges.
Cartridge type | Agilent part number | |
|---|---|---|
5 µL cartridge | 25 µL cartridge | |
AssayMAP Protein A (PA-W) cartridge rack | G5496-60000 | G5496-60018 |
AssayMAP Protein G (PG-W) cartridge rack | G5496-60008 | – |
AssayMAP Streptavidin (SA-W) cartridge rack | G5496-60010 | G5496-60021 |
AssayMAP Resin-Free cartridge rack This cartridge can be used for mock runs or as cartridge placeholders if only partial columns of Protein A, Protein G, or Streptavidin 5- or 25-µL cartridges are required. For details, see Preparing the sample plates. | G5496-60009 | – |
For more details about the available cartridges, see the Agilent AssayMAP Bravo Cartridges Selection Guide or the AssayMAP Cartridges page on Agilent.com.
Cartridge use and storage guidelines
See the cartridge box label for storage guidelines.
Follow these guidelines to get the best performance from AssayMAP cartridges:
• Use only primed and equilibrated cartridges.
Cartridges ship dry and, therefore, contain air entrained in the resin bed. Failure to prime the cartridges can prevent the reagents and buffers from accessing parts of the resin bed, resulting in reduced capacity and poor reproducibility.• Do not allow wetted cartridges to dry out.
Note: Cartridges will not dry out during the course of a normal application run. Cartridges can dry out if they are exposed to air for extended periods (e.g., >1 hour) after they have been primed and equilibrated.
If you need to store primed and equilibrated cartridges for a short period, ensure that you use the lidded blue rack-receiver plate stack with an appropriate solution in the receiver plate chimneys such that the cartridge tips are submerged in the solution.
• AssayMAP cartridges are intended to be single-use consumables. Agilent does not provide a performance guarantee for cartridges that have been used more than once.
• PA-W, SA-W, and PG-W cartridges tolerate brief exposure to pH as low as 2.0. The stability of the PA-W, SA-W, and PG-W cartridges after capturing additional affinity ligands should be determined empirically.
Labware
Labware requirements vary depending on experimental design. The following table provides a complete list of labware options and the corresponding deck locations.
The following figure shows the nine Bravo deck locations for labware.
Use only the labware specified for each deck location. Using different labware or placing labware at unapproved deck locations can cause a collision resulting in equipment damage.Figure Labware locations on the Bravo deck (top view)

Reagents
The volume, type, and concentration of reagents required for affinity purification vary depending on sample characteristics and the desired analytical result. Consult the resources that cover general principles of affinity purification such as those listed in the Reference library. For examples of reagents used with specific affinity interactions, consult the published scientific literature including publications that use the AssayMAP Bravo listed in the Agilent AssayMAP Bravo Citation Index.
By default, the syringes are rinsed thoroughly with deionized water at the wash station after completing the protocol to reduce the risk of premature syringe failure due to the buildup of salts within the syringe barrels. To perform more stringent syringe washing between runs, use the Syringe Wash utility. For details, see Syringe Wash v3.0 User Guide.
All labware require volume overage for the protocol to execute properly. Use the Affinity Purification Reagent Volume Calculator to determine volume requirements for specific protocol conditions. See Preparing the solutions.
