Detail
Introduction
Intended Use
For the detection of Salmonella spp. in food, animal feed and in environmental samples from the food production area as described in ISO 6579-1:2017.
Principle and Interpretation
Meat extract and casein provide a source of nitrogen and amino acids and sodium chloride maintain theosmotic balance. Ox bile and brilliant green act as selective agents against non-target microorganisms. Tetrathionate is generated from the sodium thiosulfate. Iodine and calcium carbonate buffer the sulfuric acid generated from tetrathionate reduction.
Formulation
Ingredients
/liter
Meat extract
4.3g
Enzymatic digest of casein
8.6g
Sodium chloride
2.6g
Calcium carbonate
38.7g
Sodium Thiosulfate (anhydrous)
30.4g
Ox bile
4.78g
pH8.0±0.2 at 25°C
Preparation
Suspend 89.4g in 1 L of purified water. Heat with frequent agitation and boil to completely dissolve the powder. Distribute into flasks，and then cool to below 45°C. Add a vial of novobiocin sodium salt (SR0640), a vial of iodine solution and a vial of brilliant green (SR0040) into 100 mL of base medium. Mix thoroughly.
Quality Control
Cultural characteristics observed after incubation at 35-37°C for 24 hours
Quality control strains
Approx. Inoculum(CFU)
Expected Results
Salmonella typhimurium ATCC14028
10 – 100
≥ 10 cfu on XLD
Escherichia coli ATCC25922
> 104
≤100 cfu on TSA
Enterococcus faecalis ATCC29212
> 104
<10 cfu on TSA
Storage and Shelf Life
2-30℃，Keep container tightly closed, avoid direct sunlight.
Use before expiry date on the label.
Precautions
1. When weighing the dehydrated medium, please wear masks to avoid causing respiratory system discomfort
2. Keep container tightly closed after using to prevent clumping.
Waste Disposal
Microbiological contamination was disposed by autoclaving at 121°C for 30 minutes.

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
These kits provides a rapid method for the purification of total RNA from non-preserved saliva and nasal/throat swabs, and from preserved saliva collected on Norgen’s Saliva RNA Collection and Preservation Devices Dx (Cat. 53800) or preserved swabs collected in Norgen’s Total Nucleic Acid Preservative Tubes Dx (Cat. Dx69200). Purification is based on using Norgen’s proprietary resin separation matrix. RNA is preferentially purified from other cellular components such as proteins, without the use of phenol or chloroform. The chemistry employed in the kit allows the purification of total RNA, including viral and bacterial RNA, irrespective of size or GC content. The purified RNA is ideal for in vitro diagnostic use for medical purposes.
Saliva/Swab RNA Purification Kit Dx (Spin Column)
This kit is optimized to be used with any downstream application employing enzymatic amplification or other enzymatic modifications of RNA followed by signal detection or amplification. Any diagnostic results generated using the RNA isolated with Norgen’s Saliva / Swab RNA Purification Kit Dx in conjunction with an in vitro diagnostic assay should be interpreted with regard to other clinical or laboratory findings.
To minimize irregularities in diagnostic results, suitable controls for downstream applications should be used.
Norgen’s Saliva/Swab RNA Purification Kit Dx is intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.
Norgen’s Saliva/Swab RNA Purification Kit Dx does not provide a diagnostic result. It is the sole responsibility of the user to use and validate the kit in conjunction with a downstream in vitro diagnostic assay.
