This grid is the typicaldesignation of body materials. Slight variations may occur due to raw material availability.1) Note the material designation imprinted on the valve body or associated tag. The marking includes the valve style, size letter, and body material.
Radial immunodiffusion (RID) is a technique that can quantitatively. determine the concentration of an antigen. Unlike many gel and liquid. precipitation techniques which qualitatively detect antigen, RID is a. sensitive quantitative technique that is often used clinically to detect. patient levels of blood proteins.
In contrast, the MAGPIXÂ® system (Figure 1) immobilizes beads with magnetic force, excites them using light-emitting diodes (LEDs), and detects beads and analytes using a CCD camera. The result is a more compact, robust, and cost-effective multiplexing tool. In addition, streamlined startup and shutdown protocols, and minimal maintenance requirements make the system easy to useâideal for both new and experienced users. The MAGPIXÂ® system can read up to 50 unique magnetic bead regions.
