How can you use “pr” in a sentence? Here are some example sentences to help you improve your vocabulary:

PCR 1 could be reliably reproduced by PCR 2 (mean PCR 1 = 4.25, mean PCR 2 = 4.26, mean PCR 1 - PCR 2 = 0.12), but the strength of coordination (PR) was not likewise reproducible by PP (see also Fig.
Only ~2,600 of this can be accounted for by the V5 eiptope and poly-histidine tail that are appended to the C-terminus of pR by the pBAD-TOPO expression vector that we used [ 1 ] . There is undoubtedly a further post-translational modification of unknown nature.
Is this an example of good PR?
Two types of parameters are calculated to reduce the information given by the frequency distribution: (i) the weighted phase coordination ratios PCR 1 and PCR 2 - see Footnote 4 - and (ii) the strength of coordination denoted as phase recurrency (PR) and pattern predominance (PP), respectively - see Footnote 5. The latter are simply defined as the mean of the two maximal f values in vertical direction and quantify the 'vertical gravity' of the gray-scale maps f 1 and f 2 . PCR 1 and PCR 2 can be interpreted as the 'vertical centers of gravity' and are defined as the weighted averages of the m :2 frequency ratios:
DCIS = ductal carcinoma in situ ; ER = estrogen receptor; HB = homeobox; HD = homeodomain; PR = progesterone receptor; RT-PCR = reverse transcription polymerase chain reaction.
