Biomolecule transfer system and methods

A protein transfer system, comprising:

• at least one base configured to receive one or more consumable protein transfer stacks;
• at least one lid engaged with and moveable relative to the at least one base, the at least one lid being configured to cover the at least one base, the at least one lid comprising one or more electrodes for supplying current to the one or more consumable protein transfer stacks,
• at least one voltage source comprised in the at least one base and configured to supply the current to the one or more consumable protein transfer stacks;
• one or more processors;
• and
• one or more hardware storage devices storing instructions that are executable by the one or more processors to configure the protein transfer system to control operation of the at least one voltage source,
• wherein the instructions are executable by the one or more processors to configure the protein transfer system to perform a consumable detection operation, the consumable detection operation comprising:
• closing a consumable detection current path, the consumable detection current path including the one or more electrodes for directing current through the one or more consumable protein transfer stacks, the consumable detection current path further including a dummy load configured to restrict current flow through the consumable detection current path;
• applying a consumable detection voltage to the consumable detection current path;
• measuring a consumable resistance resulting from the consumable detection voltage being applied to the consumable detection current path;
• determining whether the consumable resistance satisfies a consumable detection condition;
• and
• in response to determining that the consumable resistance satisfies the consumable detection condition, opening the consumable detection current path and closing a protein transfer current path, the protein transfer current path including the one or more electrodes for directing current through the one or more consumable protein transfer stacks, the protein transfer current path omitting the dummy load.
