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.

Name of Product

HAMA – Human Anti Mouse
Antibodies Detection Kit

Catalog Number

MQHM Z

Short Info

Lateral Flow Assay designed for the detection of Human Anti Mouse Antibodies (HAMA) in human serum.

This product is only available in the EU!

Method/Platform

Lateral Flow

Range/Assay Sensivity

97%

Test Principle

The HAMA Detection Kit is an immunoassay designed for qualitative determination of Human Anti Mouse Antibodies in human serum.

HAMA from patient’s sample bind first to mouse antibodies which are conjugated to gold nanoparticles.

In a second step the HAMA will be caught by mouse IgG antibodies, coated on the Test Line (T) of the nitrocellulose membrane.

In the presence of the HAMA-conjugat-complex  a band becomes visible at the location of the Test Line (T).

The surplus of gold particles continues to migrate through the membrane and is captured at the Control Line (C) by specific antibodies.

Color’s intensitiy of the test line is directly proportional to the HAMA concentration in the sample.

Introduction

This kit provides fast purification of high-quality RNA from cells, tissues, and yeast using silica-membrane spin columns with a binding capacity of 100μg RNA. There is no need for phenol/chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation or isopropanol precipitation. RNA purified using the HiPure Total RNA Purification System can be used for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Principle

The Kit isolates total RNA from up to 10⁷ cells or 20 mg tissue. A short workflow enables RNA isolation with genomic DNA removal in less than 25 mins. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column, ethanol is added to the flow-through, and the sample is applied to a RNA column. RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30µl water using the Kit.

Advantages

• Efficient removal of DNA – unique genomic DNA removal column without DNase treatment
• High quality – high purity total RNA can be directly used in various sensitive downstream applications
• Fast – several samples can be extracted in 25 minutes by column method
• Safe – no phenol chloroform extraction required
• Sensitive – RNA can be recovered at the level of PG
