Overview
Quantified standard to be used as a positive control or PCR quantification standard
Vigorously quantified using multiple methods
Listeria monocytogenes has emerged as a significant foodborne pathogen that poses a serious public health problem. As the causative agent of Listeriosis, L. monocytogenes has the highest rate of fatality among all foodborne pathogens. L. monocytogenes is a facultatively intracellular, Gram-positive bacterium. Due to its ability to survive high and low temperatures as well as low pH, it could resist various food processing technologies, as well as grow at food storage temperatures. L. monocytogenes is known to be associated with raw meat, unpasteurized milk and dairy products, vegetables, and seafood. As little as 1000 organisms may cause the disease with pregnant, new-born, and immunocompromised individuals being the most susceptible.
Norgen’s Listeria monocytogenes Quantified Bacterial DNA Standard is prepared from cultured bacteria using Norgen’s sample preparation technology. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as a positive control or PCR quantification standard for Listeria monocytogenes.
Upon receipt, store Norgen’s Listeria monocytogenes Quantified Bacterial DNA Standard at -20oC or lower. Avoid multiple freeze-thaw cycle. If needed, prepare smaller working aliquots and store at -20oC or lower.
The NGS Single Stranded DNA Library Prep Kit (illumina platform) was developed for construction of high quality libraries using sheared single stranded DNA (50 ng – 500 ng) as input. The kit is ideal for making NGS libraries with samples of denatured DNA, viral DNA, highly degraded ancient DNA and other single stranded DNA. The workflow of the ssDNA kit is simple: make the libraries in two steps followed by PCR and cleanup steps. The libraries will be ready in just 1.5 hours with a 10 minutes of hands-on time. The library pooling is possible dependent on the type of index. The final library is strand specific.
NGS Single Stranded DNA Library Prep Kit workflow
Three index types are available for the kit:
Non-index (Cat.# 30081): Libraries do not have index.
Index(Cat.# 30082): Each of the index primers has a unique 6-base index sequence that can be used to identify libraries. ssDNA library multiplexing is up to 48 samples. Index information can be downloaded here.
Unique dual index (Cat.# 30083): ssDNA sample multiplexing up to 96 libraries is possible with unique dual indexes. We have developed a Four-Base Difference Index System. This makes it possible to generate indexes with at least 4 bases different from each other in the 8 bases index length. The unique dual indexing primers remove NGS errors (example: de-multiplexing errors, read mis-assignment, index hopping etc). Index information can be downloaded here.
Kit advantages:
Quick and simple Protocol
Quick: Total protocol time is only 1.5 hours
Simple: Hands-on time only 10 minutes
Easy procedure based on:
The ready-to-use master mix: Made reaction setup easy
Less reaction components: Simplify the reaction preparation
Less magnetic beads needed: Reduced more than 50% of the beads for cleanup steps
Directional library
Single stranded DNA as input: From 50 ng to 500 ng
NGS Single Stranded DNA Library Prep Kit has similar library conversion efficiency and yield as compared to a regular DNA library prep kit.
Alignment rate and duplication rate: comparison of single stranded DNA library kit versus double stranded DNA library prep kit.

Chlamydia trachomatis, the causative agent of Chlamydia, is a Gram negative bacteria. Transmission of the bacteria occurs via contact with infected bodily fluids which then infect mucosal membranes. It can be transmitted from mother to child during pregnancy and infect the eyes causing conjunctivitis. The genital infection causes urethritis, epididymitis and prostatitis in males and Pelvic Inflammatory Disease (PID) in females with an increased risk of contracting HIV. The infection can be treated with a course of antibiotics. Sexually transmitted infections in females are most often asymptomatic, but can be noticeable in chronic pain of the pelvic region, vaginal bleeding and painful urination. Infection of the ovaries, fallopian tubes or uterus causes Pelvic Inflammatory Disease (PID) which can lead to difficulties in conceiving, increased risk of ectopic pregnancy or infertility. Infections in males are more likely to be symptomatic, causing painful urination, discharge from the penis and swollen testicles and may eventually cause infertility if left untreated.

Nuclease-free water
Can be used together with Norgen’s PCR Master Mix (#28007) or customer supplied master mix
For research use only and NOT intended for in vitro diagnostics.
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.
