The 14 exons and exon–intron boundaries of the IDUA gene were amplified from DNA samples. Primers and PCR reaction conditions have been previously described (Beesley et al., 2001 (link)). Sanger sequencing of each one of the 14 exons was performed according to the manufacturer’s protocol on an ABI Prism 3500XL (Applied Biosystems). PCR products containing mutations were re-sequenced in both directions. The mutations were further confirmed where possible by restriction analysis (data not shown).
Abi prism 3500xl
The ABI PRISM 3500xl is a genetic analyzer designed for DNA sequencing and fragment analysis. It uses capillary electrophoresis technology to separate and detect fluorescently labeled DNA fragments. The system provides high-throughput performance and can process multiple samples simultaneously.

IDUA Gene Sequencing Protocol
The 14 exons and exon–intron boundaries of the IDUA gene were amplified from DNA samples. Primers and PCR reaction conditions have been previously described (Beesley et al., 2001 (link)). Sanger sequencing of each one of the 14 exons was performed according to the manufacturer’s protocol on an ABI Prism 3500XL (Applied Biosystems).

ARSB Gene Mutation Screening Protocol
The eight exons and exon–intron boundaries of the ARSB gene were amplified from DNA samples. Primers and PCR reaction conditions have been previously described (Petry et al., 2003 (link)). Sequencing was performed according to the manufacturer’s protocol on an ABI Prism 3500XL (Applied Biosystems).
Blood specimens (unidentified) were provided by the neonatal screening center in Makhachkala (Republic of Dagestan). PCR-RFLP analysis using PspN4 I (GGN∧NCC) restriction endonuclease (SibEnzyme, Russia) was developed for the detection of NM_000046.5:c.194C>T mutation. To estimate the frequency of the NM_000046.5:c.194C>T mutation, 500 DNA samples were examined.
The frequency of the disorder was calculated from the Hardy–Weinberg equation: p2+ 2pq + q2 = 1. The confidence interval for frequencies was calculated by the Wilson method.

16S rRNA Gene Sequencing for Bacterial Identification
The search for homologous sequences and related type strains was performed using the NCBI GenBank database (https://www.ncbi.nlm.nih.gov) and the BLAST program (https://blast.ncbi.nlm.nih.gov/Blast.cgi). The phylogenetic tree was constructed using the MEGA7 program and the neighbour-joining method (Tamura et al., 2011) (link). The evolutionary distances were computed using the maximum composite likelihood model.
The rrs sequences were deposited to the NCBI Gen-Bank database under accession numbers: MT912817-MT912845.
Genetic Analysis of Freshwater Fish
For genotyping on an automated sequencer, the forward primer of each locus was prepared according to the method described by Schuelke (2000) (link), which allow the labeling of PCR products with fluorescent molecules (FAM, HEX, NED, or PET). PCR was performed as previously described (Ferreira et al., 2013) (link) with specific annealing temperatures as described for each primer (Zaganini et al., 2012; Ferreira et al., 2013) (link). The electrophoresis of PCR products was performed in an automated sequencer, ABI PRISM 3500-XL (Applied Biosystems, Foster City, CA, USA), using the GeneScan 600 Liz (Applied Biosystems) molecular weight marker. Genotypes were determined manually using the GeneMarker 1.85 software (Soft Genetics, State College, PA, USA).
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
