Plant Fluorescent Fusion Vector and Organelle Marker Co-localization Service
Fluorescent Fusion and Marker Design
CD BioSciences provides plant fluorescent fusion vector and organelle marker co-localization services for subcellular localization projects requiring construct design, marker selection, and confocal imaging support.
This service is suitable for researchers who need GFP, RFP, mCherry, or related fluorescent fusion constructs and marker-based localization interpretation.
Service Overview
Fluorescent fusion design is a critical step for plant protein localization experiments. Tag position, stop codon strategy, linker design, signal peptide preservation, and marker channel selection can all affect the quality and interpretation of confocal imaging results.

Fusion Vector Design
Useful when the C-terminus should remain free, but may disrupt N-terminal signal peptides or targeting sequences.
Common for many localization projects, but may interfere with C-terminal retention or targeting motifs.
Flexible linkers may reduce steric effects between the target protein and fluorescent tag.
Constructs can be verified by colony screening and Sanger sequencing before expression and imaging.
Marker Co-localization Design
Marker selection should match the biological question and the expected localization pattern. Channel compatibility and bleed-through risk should be considered during marker planning.

| Marker Category | Typical Use |
|---|---|
| Nuclear marker | Supports nuclear localization or nuclear exclusion analysis. |
| Plasma membrane marker | Helps interpret peripheral or membrane-associated signals. |
| ER or Golgi marker | Supports secretory pathway localization analysis. |
| Mitochondria or chloroplast marker | Supports organelle-targeting interpretation. |
| Plasmodesmata-related marker | Can be included when punctate peripheral localization is biologically relevant. |
