Real-World Testing: Putting BD Fluorescent Dyes, BD Biosciences 354217 Calcein Am to the Test

First Use Experience

I tested the BD Fluorescent Dyes, BD Biosciences 354217 Calcein Am on a standard human fibroblast cell line in a controlled laboratory setting. The assay was performed under standard cell culture conditions (37°C, 5% CO2) to mimic typical experimental conditions.

The dye performed reliably in ambient light conditions as well as with controlled exposure during imaging. Maintaining consistent temperature during the assay and imaging process is crucial for accurate readings.

The ease of use was remarkable; the protocol provided by BD Biosciences was clear and concise. After adding the reconstituted dye to the cell culture, incubation was followed by immediate visualization under a fluorescence microscope, no extensive washing steps required.

One minor initial issue was determining the optimal concentration for my specific cell line. The recommended concentration was a good starting point, but some fine-tuning was necessary to achieve optimal staining without artifacts.

Extended Use & Reliability

After several weeks of consistent use, the BD Fluorescent Dyes, BD Biosciences 354217 Calcein Am continued to provide reliable results. The dye’s performance remained consistent across multiple experiments and cell lines.

The Calcein Am itself exhibits excellent stability when stored properly, showing no noticeable degradation over several months. The only wear and tear, if any, pertains to careful handling of the vial and proper reconstitution practices.

Maintenance involves primarily proper storage of the lyophilized dye and careful handling of the reconstituted solution. Following recommended storage conditions ensures long-term stability and consistent performance.

In comparison to previous assays using trypan blue, the BD Fluorescent Dyes, BD Biosciences 354217 Calcein Am significantly outperformed the traditional method in terms of accuracy and ease of use. The reduction in cytotoxicity was also a significant advantage.

Breaking Down the Features of BD Fluorescent Dyes, BD Biosciences 354217 Calcein Am

Specifications

• Description: The BD Fluorescent Dyes, BD Biosciences 354217 Calcein Am is a cell-permeant dye used for determining cell viability. It is non-fluorescent until it enters a live cell and is cleaved by intracellular esterases, releasing free calcein, which emits a strong green fluorescence.

• Application: The primary application is to determine cell viability in eukaryotic cells. It is widely used in cell-based assays, toxicity studies, and cell migration experiments.

• Size: The product comes in a 1 mg vial. This size is typically sufficient for numerous assays depending on the experimental scale and cell density.

• BD No.: The product is identified by the BD Biosciences catalog number 354217. This ensures accurate ordering and identification of the specific reagent.

These specifications are important because they define the scope and limitations of the reagent. The cell-permeant nature ensures effective staining of live cells, while the enzymatic activation mechanism guarantees accurate viability assessment. The 1 mg size is practical for research labs, and the BD Biosciences catalog number facilitates easy reordering.
