Cell Tagging With Secondary Antibody-Magnetic Particle Conjugate... 

To tag with secondary antibody-magnetic particle conjugate add 10 pL of anti PE-MACS microbeads antibody conjugate per 106 cells, incubate at 4°C for 15 min and wash twice with the PBS buffer. Set aside 1 x 106 cell aliquot for FACS analysis. Determine the total cell concentration, and population viability using a hemacytometer and Trypan blue stain. 

G)-coated beads (e.g., magnetic particles) and identified by mass spectrometry. This procedure provides a means to metabolically tag glycosylated moleclues in situ and identify specific proteins, out of the hundreds that potentially undergo this modification, that are associated with a particular cellular process or disease state. 

Figure 14.4. Particle-based protocols for electrochemical detection of DNA. These assays involve the introduction of the probe-attached onto the magnetic particles, addition of the target/hybridization event, magnetic removal of unwanted materials, binding of the metal, and amplified electrochemical detection of the dissolved gold [Au] (A], silver (Ag] [B), and cadmium sulfide (CdS] (D) nanoparticles. Me metal tag. Also shown are solid-state stripping (C] and multitarget (E) detection protocols.

These magnetic particles are used in many applications that involve their immobilization and transpxjrt in the presence of magnetic field, or magnetically tagged biological entities due to the intrinsic penetrability of magnetic fields into human tissue. 

Rated capacity must be determined at significant load centers, including the midpoint of the extension and at the tip. Once determined, the rated capacity and load center information must be shown by stamping or tagging the extensions in a protected location of low stress. The proof load test must be witnessed by a mechanical engineer or designer. Whenever evidence of deterioration is detected or whenever the extensions have been overloaded, magnetic particle inspection must be performed. 

Lactose and biotin-tagged glycopolymer could effectively absorb ricin and the obtained toxin-glycopolymer conjugate could be transferred onto streptavidin-modified magnetic particles for decontamination (Fig. 17) [81]. 

A third method consists of measuring the time taken for a tagged panicle (e.g. radioactive or magnetic) to travel between two points 75 . The method gives results applicable only to an isolated particle which may not be representative of the bulk of the particles. These techniques can readily be used in experimental equipment but are not practicable for industrial plant.
