Usages:
For the rapid detection and enumeration of Escherichia coli.
Principle:
Peptone and yeast extract powder provides carbon and nitrogen sources and trace elements; sodium chloride maintains osmotic equilibrium; agar as medium coagulant; dodecyl sulfate inhibit Gram-positive bacteria; chromogenic substrate and large intestine coli β- glucuronidase enzyme specific reaction, hydrolysis of the substrate, the release of the color groups produce green colonies on the light yellow plate.

Peptone :15.0g
Yeast extract powder: 3.0g
Sodium chloride: 5.0g
Sodium lauryl sulfate:0.1g
Agar: 12.0g
Chromogenic substrate 6.5g
Final pH 7.0 ± 0.2
How to use:
1. Weigh 41.6g of the product, adding 1.0L distilled or deionized water, heated to boiling stirring until completely dissolved, dispensing into flask, 115 autoclaved for 10minutes.
2. Take 25.0g or 25.0ml of sample with sterile procedures , added to the flask containing 225.0mL of sterile phosphate buffered saline (or saline) , shaken thoroughly homogenized with a homogenizer or a 1:10 dilution of 1min solution, diluted 1:10 and then continue to select the appropriate serial dilutions of three, the two plates inoculated with each dilution, poured dissolved by heating and cooled to about 45 medium.
3, observe the results.

Description
Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.
Key Features
Storage and stability
Store Q-PAGE™ Precast Gels at 4°C for periods up to 12 months.
Do not freeze Q-PAGE™ Precast Gels. Remove tape and comb before electrophoresis.
Keep Q-PAGE™ Precast Gels flat during storage.

Cysticercosis is caused by larval cysts of the tapeworm Taenia solium and is a major cause of adult onset seizures in most developing countries. Diagnosis is based on imaging findings, but in many cases it is not conclusive for the diagnosis. Serological assays has an important place on the final diagnosis of the disease. The ELISA kit hs shown appropriate performances for the serological screening of cysticercosis.

Short Info
Cysticercosis is caused by larval cysts of the tapeworm Taenia solium and is a major cause of adult onset seizures in most developing countries. Diagnosis is based on imaging findings, but in many cases it is not conclusive for the diagnosis. Serological assays has an important place on the final diagnosis of the disease.

This product is manufactured by Bordier Affinity Products in Switzerland and distributed in Germany exclusively by Milenia Biotec.
Method/Platform
ELISA in microplate format
Range/Assay Sensivity
98% sensitivity, 98% specificity
Test Principle
The kit provides all the material needed to perform 96 enzyme-linked immunosorbent assays (ELISA) on breakable microtitration wells sensitized with Taenia solium cyst soluble antigens. Specific antibodies in the sample will bind to these antigens and washing will remove unspecific antibodies. The presence of parasite specific antibodies is detected with a Protein A – alkaline phosphatase conjugate. A second washing step will remove unbound conjugate. Revealing bound antibodies is made by the addition of pNPP substrate which turns yellow in the presence of alkaline phosphatase. Color intensity is proportional to the amount of Taenia solium specific antibodies in the sample. Potassium phosphate is added to stop the reaction. Absorbance at 405 nm is read using an ELISA microplate reader. The test can be performed with automatic systems, but this must be validated by the user.
