Create mode – the default mode when you create a requisition and PunchOut to Bio-Rad. You can create and edit multiple shopping carts
Edit mode – allows you to edit or modify an existing requisition (prior to submitting). You will be able to modify only the cart that you have PunchedOut to, and won't have access to any other carts
Inspect mode – when you PunchOut to Bio-Rad from a previously created requisition but without initiating an Edit session, you will be in this mode. You cannot modify any Cart contents
Ideal tools for monitoring protein purification progress
Epitope tagging is a technique in which a known epitope is fused to a recombinant protein using genetic engineering. Bio-Rad offers one polyclonal and three monoclonal s-tag antibodies; clones SBSTAGa, SBSTAGb, SBSTAGc. Each monoclonal is available in different formats including FITC, HRP purified and RPE suitable for use in ELISA, flow cytometry and protein purification. These s-tag antibodies are fusion peptide tags derived from pancreatic RNase A that are widely used in protein expression applications.
S-tag is a 15 amino acid truncated form of the S-peptide, KETAAAKFERQHMDS, used in variety of protein expression applications in mammalian cells.
