Overview
Detection kits for Neisseria gonorrhoea
Available in TaqMan format for analysis
Neisseria gonorrhoeae is a Gram-negative coccus of the Neisseria genus. N. gonorrhoeae is usually seen in pairs infecting human cells. It has a circular DNA genome of approximately 1Mbp encoding over 2000 genes. N. gonorrhoeae is transmitted by sexual contact and usually causes infection in cells of the mucous membrane of the male urethra or the endocervix and urethra in females. During infection, polysaccharides are released from the bacteria that stimulate host cell production of tumour necrosis factors that cause an inflammatory response.
There is no vaccine against N. gonorrhoeae infection and antibiotic resistance is beginning to increase, therefore treatment includes a course of antibiotics that will be effective against resistant strains. Complications in males caused by the infection can result in prostatitis or orchitis if the bacteria spread. In females, invasion of the fallopian tubes or ovaries can result in salpingitis or ovaritis respectively, with any of these infections possibly resulting in sterility.
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.
Extract total RNA (including microRNA) from FFPE samples
No phenol extraction step
Includes DNase for optional on-column DNA removal
Isolated RNA is of the highest quality and integrity
Isolate a diversity of RNA species
Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
Norgen’s FFPE RNA Purification Kits provide a rapid method for the isolation and purification of total RNA (including microRNA) from formalin-fixed paraffin-embedded (FFPE) tissue samples in as little as 1 hour. Using formalin to fix tissues leads to crosslinking of the RNA and proteins, and the process of embedding the tissue samples can also lead to fragmentation of the RNA over time. Norgen’s FFPE RNA Purification Kits provide conditions that allow for the partial reversing of the formalin modifications, resulting in a high quality and yield of RNA. These kits are able to purify all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA), depending on the age of the FFPE tissue as fragmentation of the RNA is known to occur over time. The RNA is preferentially purified from other cellular components without the use of phenol or chloroform.
FFPE RNA Purification Kit (Spin Column)
Maximum loading volume of 650 μL per column, and a maximum binding capacity of 50 μg per column.
Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. Purification can be performed using either a vacuum manifold or centrifugation. Maximum loading volume of 400 μL per well, and a maximum binding capacity of 50 μg per well.
5 slices of < 20 µm thick paraffin slices 25 mg of unsectioned block
Average Yield
Variable due to age of paraffin blocks ~2-3 µg of Total RNA per 1 mg of fresh FFPE hamster kidney
* Time required for purification varies by length of Proteinase K incubation and formalin crosslink-reversal
Storage Conditions and Product Stability All solutions should be kept tightly sealed and stored at room temperature. The DNAse I and Proteinase K should be stored at -20°C upon arrival. This kit is stable for 1 year from the date of shipment.
The 16S V3-V4 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V3-V4 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V3-V4 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V3-V4 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.
Details
Minimum amount of starting material:
2.5 µL of DNA (5 ng/µL)
Time to complete library preparation:
4 hours
Storage Conditions and Product Stability Norgen’s 16S V3-V4 Library Prep Kit for Illumina is shipped as one kit box (for the 24 prep kit) or two sub-component kits (for the 96 prep kit). All kits should be stored at -20°C upon arrival.
All kit components should remain stable for at least 1 year when stored at the specified storage conditions.
