Format: particles, plasmids, and viruses

As with many of the other RNAi Specs filters, our AI extracts Format from vendor information and databases. There could be some confusion about what different formats mean, so here's a quick summary:

Viral particles – Your plasmid and RNAi payload are encapsulated/packaged in a virus (e.g. lentivirus, adenovirus, etc.), ready for transduction.

Plasmids – A DNA construct, comprising bacterial and/or viral promoters, to transfect target cells or packaged for viral transduction. May come as a bacterial glycerol stock.

Virus – Often synonymous with viral particles. Category was mined from the vendor.

In principle, we classify products using the narrowest categorization we can infer from the vendor. For example, if a vendor categorizes a reagent as a lentiviral particle, although it might also fit in with our lentivirus Format, lentiviral particle is a narrower, more specific category so that is what we use.
