CellLight™ Early Endosomes-RFP, BacMam 2.0

CellLight Early Endosomes-RFP, BacMam 2.0, provides an easy way to label early endosomes with red fluorescent protein (RFP) in live cells. Simply add the reagent to your cells, incubate overnight, and the cells are ready to image in the morning.

This ready-to-use construct is transfected into cells using BacMam 2.0 technology, where it expresses RFP fused to Rab5a. You can observe early endosomes-RFP behavior in live cells independently of organelle pH and label with 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.

CellLight Technology is:
• Fast and convenient: simply add CellLight reagent to your 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

BacMam Technology
CellLight Early Endosomes-RFP, BacMam 2.0, is a fusion construct of Rab5a and TagRFP, providing accurate and specific targeting to cellular Early Endosomes-RFP. 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.
