dim_samples - Instance

The table that contains information about all physical samples processed in the assay. Each sample represents a distinct reaction vessel containing a specific candidate library exposed to a defined antigen concentration and biochemical condition. Other tables reference this table using sample identifiers (such as sample_id, binding_sample_id, or expression_sample_id) to look up assay parameters and experimental conditions. Grain: one row per sample_id.

Column	Type	Description
`sample_id`	`string`	Uniquely identifies a physical sample in the run. Other tables reference this value to indicate which sample a record came from.
`sample_plan_id`	`string`	Identifies this sample specification established during the Planning stage, before experimental execution.
`candidate_library_id`	`string`	Identifies the pooled candidate library that was expressed and tested.
`candidate_library_plan_id`	`string`	Identifies this candidate library specification established during the Planning stage, before experimental execution.
`sino_catalog_id`	`string`	Identifies the antigen using its Sino Biological catalog number. Empty for samples that were not run against an antigen.
`antigen_concentration_nM`	`float`	Concentration of the antigen used in this sample, in nanomolar (nM).
`antigen_gene_name`	`string`	Gene name of the antigen.
`antigen_sequence`	`string`	Amino acid sequence of the antigen.
`translation_condition`	`string`	Describes the biochemical redox environment applied during in vitro translation, such as reducing or disulfide conditions, to facilitate proper candidate folding.
`selection`	`boolean`	Indicates whether the sample underwent antigen binding selection. `true` marks a binding sample exposed to an antigen; `false` marks a baseline expression sample.
