Harvesting

Harvesting

1. (Science: cell culture) The collecting of cells, organisms, or the growth medium upon which an experimental population (of cells or microorganisms) had grown, so that the collection can be analysed or so biochemicals can be extracted from it.

2. (Science: zoology) harvesting ant, any species of ant which gathers and stores up seeds for food. Many species are known.

The species found in southern Europe and Palestine are Aphenogaster structor and a. Barbara; that of Texas, called agricultural ant, is pogonomyrmex barbatus or Myrmica molifaciens; that of Florida is pogonomyrmex crudelis.

Learning tissue culture, specifically moDC generation

... with antigen (or alternatively first pulse the DCs with antigen for 4 hours in +37C and wash). The cells are stuck quite firmly to the plate, so harvesting may break some of them. Use of EDTA or some other such ion-binding substance may help removing the cells alive. Use a microscope to make ...

Re: Cellular respiration questions..

... glucose, which results in the C6 molecule splitting and C3 pyruvate resulting (G3P). The energy investment step requires 2 ATP, and the energy harvesting step produces 4 ATP. Totaling in a net gain of only 2 ATP. During the krebs cycle enzymes pass high energy PHOSPHATE to ADP, which results ...

Incubation of Soil Fungi

... One or a 1000 distinct fungal cells can give 1 cfu. Similarly serial dilution is invalid procedure to reduce inoculum concentration. You could try harvesting and resuspending conidiospores but precise measurment even with these is not readily obtained and multicellular mycelial fragments and conidiospores ...

Re: What are delocalized electrons?

... they have slightly different absorption spectra, so chl b works as additional pigment. Similarly as carotenoids. Look for structure of light harvesting complex ( this one is little better for you). I'm linking to Wikipedia, because it's (relatively) good starting point, but it's of course ...
