Sample ID: “1-VH” and “1-VHH” represent the NO.1 camel`s conventional antibody and nanobody clones, respectively. The same nomenclature is used in the other samples. Raw data are the total number of reads; Clean data (%) is the rate of the filtered sequence reads, with the low-quality data removed; Merged (%) is the percent of sequences generated by merging the pair-end reads to one intact read; V-align (%), J-align (%) and VJ-align (%) are percentages of the sequencing data that were matched with the IMGT reference sequences; Effective data are the number of reads after filtering; Effective data/raw data (%) is the percent of raw data that remained after filtering.
