Plasma Membrane Imaging Services

Plasma membrane, also known as cell membrane, is a natural barrier between extracellular environment and cytoplasm. Its main components are lipids and proteins. Plasma membrane plays an important role in many biological events, including cell division, signal transduction, endocytosis, exocytosis and apoptosis. At present, direct imaging and observation of the plasma membrane of living cells is still one of the most effective methods to study its role, function and its relationship with specific cell responses.

Plasma Membrane Imaging Analysis

Fluorescence imaging is considered the gold standard for optical imaging of plasma membranes. Researchers usually use organic fluorescent dyes or their derivatives to monitor cell processes and events related to plasma membranes in real time. However, due to the rapid cell internalization of fluorescent dyes and rapid separation of the dye from the membrane, it is difficult to image the plasma membrane with long-term stability. In order to extend the retention time of various fluorescent dyes on the cell membrane, CD BioSciences can develop new fluorescent probes for you to monitor the morphological changes and kinetic changes of plasma membrane during cell apoptosis for a long time.

Plasma Membrane Imaging Analysis Workflow

The following are the specific experimental steps of plasma membrane imaging analysis:

Synthetic fluorescent probe

Synthetic fluorescent probe

We will design and synthesize fluorescent probes for you according to your needs, and characterize them by NMR, dynamic light scattering and GC.

Step 1
Cell culture

Cell culture

The cells were seeded into DMEM containing FBS and penicillin/streptomycin. Incubate for 1 day in a 5% CO2 environment at 37 °C. Then remove the cell culture medium and incubate for 24 h with fresh medium containing different chromogenic agents.

Step 2
Cell staining

Cell staining

After several washing steps, the glass slide containing the sample was imaged under a STED microscope with various parameters set to observe the morphology of peroxisomes.

Step 3
Confocal fluorescence imaging

Confocal fluorescence imaging

The processed cells are imaged under a confocal laser scanning microscope to monitor the morphological changes of the plasma membrane during cell events, and confocal images are acquired at different time points.

Step 4
