When the combined library is used to analyze the normal individual urine proteome (18 males and 18 females), gender-related and age-related proteins are discovered and functionally analyzed. Use of a combined urinary protein library provides the most complete protein and peptide information, and the DIA approach can provide accurate protein quantitative information even for low-abundance proteins. The DDA mode can provide a larger spectral library than the DIA mode and the DDA-library leads to more protein identifications in the study. Includes articles on analyzing data resulting from analysis of protein binding, interactions, folding, etc.

The RPLC separation method provides more proteins for generating the library than the spin column however, the spin column library leads to identification of more proteins when used for the urine proteome analysis. In this study, an attempt is made to evaluate the influence of different sample separation methods (reversed-phase liquid chromatography (RPLC) linear gradient elution and spin column step gradient fractionation) and data acquisition modes (data-dependent acquisition (DDA) and DIA) on library generation of the human urine proteome. Optimal sequencing depth depends on the aims of the experiment and on the complexity of the target transcriptome.As an important part of the data-independent acquisition-mass spectrometry (DIA-MS) analysis approach, spectral library generation is closely related to the final protein identification and quantitation. As the sample is sequenced to a deeper level, the reads are likely to cover a larger proportion of the genome/transcriptome, allowing more transcripts to be detected with more precise quantification. Sequencing depth or library size refers to the number of sequenced reads for a given sample. Paired-end reads are preferable for de novo transcript discovery or isoforms expression analysis, as well as to characterise poorly annotated transcriptomes.

Paired-end sequencing means sequencing both ends of the cDNA fragments and aligning the forward and reverse reads as read pairs (Figure 8). Because the distance between each paired read is known, alignment algorithms can use this information to map the reads over repetitive regions more precisely. Paired-end sequencing enables boths ends of the DNA fragment to be sequenced.
