DBCO-PEG4-PFP ester is a PFP active ester containing a DBCO group which can undergo copper-free Click Chemistry with azide (N3). The PFP ester moiety is reactive with amine groups. PFP esters have been are stable compounds and are less susceptible to undergo hydrolysis. The hydrophilic PEG linker increases the water solubility of a compound in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.

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.

Introduction

HiPure Bacterial RNA Kit uses silica gel column purification to simplify the extraction. The whole process does not require phenol chloroform extraction and time-consuming alcohol precipitation. The kit is suitable for efficiently extracting RNA from various bacterial samples. The purified RNA can be directly used for RT-PCR, Northern hybridization, etc. The kit has included lysozyme and glass beads, which can be used to treat gram-negative bacteria which is easy to be lysed, as well as gram-positive bacteria which is hard to be lysed, including enterococcus faecalis, staphylococcus, etc.

Principle

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

Advantages

• Fast – several samples can be extracted in 30 minutes
• High purity – the purified RNA can be directly used in various downstream applications
• High recovery – RNA can be recovered at the level of PG
• Good repeatability – silica gel column purification technology can obtain ideal results every time
• Broad spectrum – it can deal with various bacteria, including Gram-positive bacteria that are difficult to be lysed
• Sufficient components – the kit contains carried lysozyme and glass beads

Storage and Stability

The kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions. Due to the lack of antibacterial agents, RNase Free Water may be contaminated by bacterial or fungal when placed or operated at room temperature. It is recommended to pack and store at 2-8°C to reduce contamination.
