Plant Subcellular Localization Confocal Imaging Service
Plant Protein Localization Imaging
CD BioSciences provides plant subcellular localization confocal imaging services for determining the cellular distribution of fluorescent fusion proteins in plant cells.
This service supports GFP, RFP, mCherry, and related fluorescent fusion designs, plant transient expression, marker co-expression, confocal imaging, and localization interpretation.
Service Overview
Subcellular localization analysis uses fluorescently tagged proteins to observe where a target protein accumulates in plant cells. The assay can be performed before interaction studies, after candidate gene identification, or as a standalone protein function analysis experiment.
Because tag position may affect protein localization or function, N-terminal and C-terminal fusion design should be considered carefully, especially for proteins with signal peptides, transit peptides, transmembrane regions, or known localization motifs.
Workflow

- Sequence and localization motif review
- Fluorescent fusion construct design
- Vector construction and sequence verification
- Plant transient expression or protoplast expression
- Marker co-expression, when needed
- Confocal imaging by selected channels
- Image organization and localization report
Confocal Imaging and Marker Panels
Representative image panels can include the target fluorescent fusion channel, marker channel, bright field or DIC image, and merged image. Marker co-expression can help distinguish nuclear, cytoplasmic, membrane, organelle, or punctate localization patterns.

Localization Targets
| Localization Category | Typical Imaging Consideration |
|---|---|
| Nucleus | Nuclear marker or DNA-associated context can support nuclear localization interpretation. |
| Cytoplasm | Diffuse signal should be interpreted together with expression level and background. |
| Plasma membrane | Peripheral signal may require marker support to distinguish membrane localization from cell boundary effects. |
| ER, Golgi, mitochondria, or chloroplast | Organelle markers and channel separation are useful for co-localization interpretation. |
| Punctate or vesicle-like patterns | Multiple fields and marker comparison are often needed for careful interpretation. |
