Workflow
-
Required Starting Materials:
- Target Protein: Purified protein with known concentration and characterization data (e.g., SDS-PAGE, purity assessment).
- Desired Fluorescent Label: Specific fluorescent dye or fluorophore, or clear criteria for selection based on excitation/emission wavelengths, brightness, and photostability.
- Specific Application/Experimental Goals: Detailed information on how the labeled protein will be used (e.g., live-cell imaging, immunofluorescence, flow cytometry) and any specific functional requirements.
- Key Steps Involved:
| Step | Activities | Expected Outcomes |
|---|---|---|
| Project Consultation & Design | Our specialized team collaborates with you to thoroughly understand your project's research goals, the specific attributes of your target protein, and the requirements of its intended application. We collaboratively select the appropriate fluorescent probe and design an optimal conjugation strategy (e.g., amine, thiol, site-specific labeling). | A comprehensive project plan outlining the chosen labeling method, dye selection, and quality control parameters, ensuring alignment with your research goals. |
| Fluorescent Conjugation | Utilizing advanced bioconjugation techniques, our scientists execute the chosen labeling method under carefully controlled reaction conditions to achieve efficient and site-specific attachment of the fluorescent dye to your target protein, while preserving its native structure and function. | The protein will be successfully conjugated with the fluorescent label, primed for subsequent purification and detailed characterization. |
| Purification & Characterization | Following conjugation, the labeled protein undergoes rigorous purification to eliminate any unbound dye and reaction byproducts. We then perform extensive quality control analyses (e.g., SDS-PAGE, MS, UV-Vis, fluorescence spectroscopy, functional assays) to confirm successful labeling, purity, and functionality. | Highly pure, well-characterized fluorescently labeled protein with confirmed labeling efficiency and spectral properties. |

FAQs
Q: What types of fluorescent dyes can Creative Biolabs use for protein labeling?
A: Creative Biolabs offers a wide selection of fluorescent dyes, including various small molecule dyes (e.g., fluorescein, rhodamine derivatives, cyanine dyes), fluorescent proteins (e.g., GFP, RFP), and quantum dots. We work closely with you to select the optimal dye based on your experimental requirements, desired excitation/emission spectra, and compatibility with your biological system.
Q: Can Creative Biolabs perform site-specific labeling on my protein of interest?
A: Yes, Creative Biolabs specializes in both random and site-specific labeling approaches. We utilize advanced techniques to ensure the fluorescent probe attaches precisely to the desired location on the protein, allowing for highly controlled and specific studies.
Q: What information do I need to provide to initiate a Custom Protein-Fluorescent Conjugation Service project?
A: To begin, we typically require information about your target protein (e.g., purity, concentration, sequence), the desired fluorescent label (or your application needs), and details about your experimental goals. This allows us to design a tailored conjugation strategy that best meets your project's requirements.
Q: How does Creative Biolabs' service compare to off-the-shelf fluorescent labeling kits?
A: While off-the-shelf kits offer convenience, Creative Biolabs' service provides unparalleled customization, quality control, and expertise.
