As pooling animals from each stage could have masked effects in individual animals, 6 animals were taken from the treated and untreated groups at stage 46 and analysed individually.
A total of 20 PI rats (five arrays, n=4 pooled animals per array) and 12 control rats (three arrays, n=4 pooled animals per array) were reserved for microarray analysis and qRT-PCR validation at each time point (total n=96).
On the other hand, when we analyzed and compared the results of individual animals with or without arthritis or spondylitis at the end of the observation period (that is, without pooling animals within a group [colony]), significant correlations were found (Table 2).
From the sex separated and age pooled animals about 1000 antennae, 600 legs, 150 mouthparts (as piece of the head capsule anterior of the antennae), 50 heads (the whole head capsule excluding the antennae) and 20 bodies (excluding head and legs) were manually dissected and immediately transferred to ice cold RNA lysis buffer (Zymo Research, Irvine, USA).
In summary, by combining pooled animal immunisation, hybridoma generation, antigen microarrays and a convenient method to identify plasmids encoding functional recombinant antibodies, we have addressed two major bottlenecks that prevented increasing the scale of a method for the parallel selection of high-quality monoclonal antibodies.
Animals of the selected sub-populations were randomly chosen from a pool of animals born after 1999 (128 465 animals) on the assumption that only recent animals could be of interest (those being genotyped or in production).
Since we were interested in identifying transcripts differentially expressed due to their direct or indirect involvement in islet morphogenesis, RNA isolated from whole pancreas tissue was pooled (3 5 animals per pool) to minimize differences associated with biological variability among samples.
And they were a highly intellectual jumble: one of them had an inflatable pool, stuffed animals and a video monitor playing Beethoven's "Ode to Joy".
Available evidence suggests that the IBAT is a major regulator of the BA pool in animals and humans.
It is possible to define a pool of animals for which estimated breeding values can be compared after an across-herds genetic evaluation, especially for highly heritable traits.
