Invitrogen™ CellLight™ Plasma Membrane-CFP, BacMam 2.0
Description
This ready-to-use construct is transfected into cells using BacMam 2.0 technology, where it expresses CFP fused to the myristolyation/palmitoylation sequence from Lck tyrosine kinase. You can observe plasma membrane-CFP behavior in live cells without staining internal membranes, and also use multiple tracking or tracing dyes to image dynamic cellular processes.
Cells expressing CellLight constructs can also be fixed with formaldehyde for multiplexed imaging using immunocytochemical techniques.
BacMam Technology
CellLight Plasma Membrane-CFP, BacMam 2.0, is a fusion construct of the myristolyation/palmitoylation sequence from Lck tyrosine kinase and CFP, providing accurate and specific targeting to cellular plasma membrane-CFP. This fusion construct is packaged in the insect virus baculovirus, which does not replicate in human cells and is designated as safe to use with biosafety level (BSL) 1 in most laboratories. BacMam technology ensures that most mammalian cell types are transduced/transfected with high efficiency and minimal toxicity. This transient transfection can be detected after overnight incubation for up to five days—enough time to carry out most dynamic cellular analyses. Like any transfection/transduction technique, the BacMam method does not transfect/transduce all of the cells with equal efficiency, making it poorly suited to cellular population studies or automated imaging/counting. CellLight reagents are ideal for experiments where cellular or subcellular co-locatization is required, or for cellular function studies that need special resolution.
- Fast and convenient: simply add CellLight reagent to cells, incubate overnight, and image—or store frozen, assay-ready cells for later use
- Highly efficient: up to 90% transduction of a wide range of mammalian cell lines, including primary cells, stem cells, and neurons
- Flexible: co-transduce more than one BacMam reagent for multiplex experiments or co-localization studies; tightly control expression levels by simply varying the dose
- Less toxic: CellLight reagents are non-replicating in mammalian cells and are suitable for biosafety level (BSL) 1 handling
- Flow Cytometer Laser Lines: 405

Frequently Asked Questions (FAQs)
Try varying particle-to-cell ratio (PPC), incubation volume, temperature and, cell density (if adherent cells are transduced). For adherent cells, we recommend a confluence of about 70%. Following the PPC, adjusting the volume is the next best parameter to change to optimize protein expression. If that doesn't work, you can also use the BacMam Enhancer Kit (Cat. No. B10107).
Cells transduced with the CellLights reagents can be stored frozen for several months after transduction, without loss of expression.
If the viral particles are used at the level we recommend, they are very well tolerated by cells.
The BacMam 2.0 CellLights typically express for 5 days after transduction.
The first generation BacMam reagents were shown to efficiently transduce over 90 cell types, including stable cell lines and primary cells. With BacMam 2.0, it is now possible to also efficiently transduce primary neurons and stem cells.
