The DM3160 FluoroBand™ 1KB (0.25-10 kb) Fluorescent DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with high sensitivity DNA binding fluorescent dye and loading dye for direct gel loading. The DNA ladder DM3160 is composed of 13 individual DNA fragments: 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 bp derived from a mixture of PCR products and specifically digested plasmid DNA; these bands can be visualized when illuminated with 470 nm blue light or UV light. This product contains two enhanced bands (3 kb and 1 kb) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Bromophenol blue which mimic the migration of 4,000 bp and 500 bp dsDNA during electrophoresis are also added for real time monitoring. Real time observation of the electrophoresis is also possible if compatible light source is fitted to the electrophoresis tank.

Overview
Detection kits for Clostridium difficile
CE-IVD marked version available for in vitro diagnostic use
Available in TaqMan format for analysis
Clostridium difficile is rod-shaped, gram positive bacterium. It is the main causal agent of antibiotic-associated diarrhea and pseudomembranous colitis. The colonization of intestines by C. difficile is usually associated with the elimination of natural intestinal flora as a result of antibiotic application and is frequently reported in health care centers. While C. difficile infection could be severe and life-threatening, particularly among the elderly, many patients are asymptomatic making diagnosis challenging during outbreaks. The tradition method of detecting C. difficile infection is by cytotoxicity test of the toxin produced by the bacterium, but such protocols usually require extensive time before conclusion can be made.
Storage Conditions and Product Stability All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
HiDi® stands for High Discrimination of mismatches at the 3’-terminus of primers in PCR. This myPOLS Biotec enzyme family is optimized for this feature and is the first choice for applications that rely on this property such as allele-specific PCR (asPCR) or allele-specific amplification (ASA).Please note: This DNA polymerase is also available as a nuclease deficient variant, featuring higher robustness towards potential PCR inhibitors and compatibility with real-time dyes such as our GreenDye.Benchmarking with products of competitors conducted by us and others show that the HiDi® DNA polymerase family is the first choice for highly selective PCRs, such as genotyping by allele-specific PCR, HLA genotyping, analysis of single CpG methylation sites or the detection of mutations in a high background of wild-type sequences. By using HiDi® Taq DNA polymerase, less than 10 copies of a mutation can be detected in a background of >10.000 wild-type copies straight away without any other tedious assay optimization.HiDi® Taq DNA polymerase harbours a nuclease function and therefor is also suitable for use with hydrolysis probes (TaqMan® probes etc.). It has also been shown that HiDi® DNA polymerase family is highly suitable for quality control and mutation identification in CRISPR-Cas or TALEN-based applications.Several independently conducted studies show that HiDi® Taq DNA polymerase is ideally suited for use in asPCR in numerous research areas ranging from mutation detection to genome editing.

Example Primer Design
Matching vs. mismatching nucleotide is placed at the 3′-end of the primer for best discrimination results.
Example Results – There´s no accounting for taste
Cilantro: some people love it in their food, some hate it. Here we are detecting a genomic SNP (rs72921001) in HeLa genomic DNA. This SNP is reported to be close to a number of genes coding for olfactory receptors. (Reference: Eriksson N. et al. (2012), “A genetic variant near olfactory receptor genes influences cilantro preference.”)
Considering, that only the C-allele specific primer is extended and yielding in a specific amplicon, we can conclude a genetic predisposition in disliking cilantro, as this SNP is significantly associated with detecting a soapy taste to cilantro.
Allele-specific PCRs were performed from 1 ng/µl of HeLa gDNA in the presence of a realtime dye, indicating the amplification of the C-allele specific primer only. The A-allele specific primer is discriminated, thus not amplified up to 50 cycles.
PCR products were subsequently analysed on a 2.5% agarose gel. Specific product is visualized by ethidium bromide staining at the amplicon length of 109 bp.
