production of primary and secondary cells

Primary and Secondary Antibodies

Problem: Fc receptors expressed by cells non-specifically bind primary and secondary antibodies.This is particularly problematic for tissues that have been damaged and contain activated immune cells. Solution: Use Fab preparations for detection rather than whole antibodies or block using unconjugated Fc fractions that match both primary and secondary antibody preparations.

Immune Responses: Primary and Secondary

 · Immune responses to antigens may be categorised as primary or secondary responses. The primary immune response of the body to antigen occurs on the first occasion it is encountered. Depending on the nature of the antigen and the site of entry this response can take up to 14 days to resolve and leads to the generation of memory cells with a high ...

Classification of Cells or Batteries

Most primary cells utilize electrolytes that are contained within absorbent material or a separator (i.e. no free or liquid electrolyte), and are thus termed dry cells. A secondary cell or battery is one that can be electrically recharged after use to their original pre-discharge condition, by passing current through the circuit in the opposite direction to the current during discharge.

The Flow of Energy: Primary Production

The rates of secondary production, as we will see in a coming lecture, are very much lower than the rates of primary production. An everyday example of how GPP, NPP, and R are related. To better understand the relationship between respiration (R), and gross and net primary production (GPP and NPP), consider the following example.

Primary cell

 · Secondary Immune Response For second and subsequent encounters with similar antigens, secondary (anamnestic) immune responses occur. Here, the lag phase is shorter, and high and steady levels of antibodies are generated within a few days. This is due to antigen-specific memory T and B cells, originally produced during the primary response.
