In an ultrasonic standing wave field, the acoustic radiation force F z rad acts on a particle that has a non-zero acoustic contrast factor, Φ.The magnitude of the force acting on the particle depends on the radius ɑ, κ 0, ρ 0, κ p and ρ p which represent the compressibility and density of the fluid and particle ...

Dynabeads® magnetic separation technology also allows you to 'see' your sample during handling due to the color of the magnetic beads. When the sample tube is placed in the magnet, the bead-bound exosomes are pulled to the side of the tube, allowing for easy separation and buffer changes.

The level of circulating tumor cell (CTCs) is a reliable marker for tumor burden and malignant progression. Quantification of CTCs remains technically challenging due to the rarity of these cells in peripheral blood. In the present study, we established a real-time quantitative PCR (Q-PCR) based met …

Magnetic separation – Place the 1.5 ml tube with bead-bound cells in the magnetic separator for 2 min. Lineage positive cells will get stuck to the tube wall. Gently pipette out unattached cells and place into a fresh 1.5 ml tube. Place the fresh tube in the magnetic and repeat magnetic depletion for a total of 3 times.

We describe a "turn-on" magnetic fluorescent biosensor based on graphene quantum dots (GQDs), Fe3O4, and molybdenum disulfide (MoS2) nanosheets. It is used for rapid, efficient, and sensitive separation and detection of circulating tumor cells (CTCs). A facile approach (electrochemical synthesis method) for the preparation of photoluminescent GQDs functionalized with an aptamer …

Methods: Density gradient centrifugation and magnetic separation based on CD45 antibody were used to isolate CTCs. 3D culture was used to maintain and amplify CTCs and HCC cells. Cellular immunofluorescence was used to identify CTCs and spheroids. ... EpCAM may participate in the formation and survival of CTC spheroids which dependent on Wnt/β ...

A microfluidic device for biomedical analysis possesses the advantages of miniaturization, automation, integration, and portability. The microfluidic reactor is an important functional unit in the lab-on-a-chip system. The performance of the lab-on-a-chip systems is directly affected by the stable and superior behavior of reactors.

Human EpCAM is a polypeptide of 314 amino acids (aa), consisting of a large extracellular domain (N-terminal) of 242 aa, a single-spanning transmembrane domain of 23 aa and a short cytoplasmic domain of 26 aa (C-terminal) (Fig. 2, Fig. 3).The gene encoding for human EpCAM is located on chromosome 2 (location 2p21) and has an estimated size of 14 kb,, .

Purpose: Circulating tumor cells (CTCs) are considered to be a key factor involved in tumor metastasis. However, the isolation and culture of CTCs in vitro remains challenging, and their clinical application for predicting prognosis and survival is still limited. The development of accurate evaluating system for CTCs will benefit for clinical assessment of HCC.

Epithelial cell adhesion molecule (EpCAM) antibody is used to couple the magnetic beads in the system. However, EpCAM positive cells have been found in healthy persons. Moreover, epithelial-mesenchymal transition (EMT), which is vital for metastasis, could result in loss of epithelial antigens in some CTCs[22-26].
