Plasma/Serum VZV PCR Detection Kit - Protocol
Contents
1. The specificity of Norgen s Plasma Serum VZV PCR Detection Kit is first and foremost ensured by the selection of the VZV specific primers as well as the selection of stringent reaction conditions The primers were checked for possible homologies in GenBank published sequences by sequence comparison analyses F Linear Range The linear range analytical measurement of Norgen s Plasma Serum VZV PCR Detection Kit was determined by analyzing a dilution series of VZV quantitative standard ranging from 8 46 x 10 VP ul to 1 x 107 IU ul Each dilution has been tested in replicates n 4 using Norgen s Plasma Serum VZV PCR Detection Kit on 1X TAE 1 7 Agarose gels The linear range of Norgen s Plasma Serum VZV PCR Detection Kit has been determined to cover concentrations from 2 VP ul to at least 8 x 10 VP ul Under the conditions of Norgen s Plasma Serum DNA Isolation procedure Norgen s Plasma Serum VZV PCR Detection Kit covers a linear range from 200VP mL Plasma Serum to at least 8 x 10 VP mL Plasma Serum G Frequently Asked Questions 1 How many samples should be included per PCR run e Norgen s Plasma Serum VZV PCR Detection Kit is designed to test 24 samples For every 6 samples a Negative Control and a Positive Control must be included It is preferable to pool and test 6 samples at a time If not the provided Negative Control and Positive Control are enough to run 3 samples at a time 2 How can interpret m2. VZV Positive Control PosC should be kept tightly sealed and stored at 20 C for up to 1 year without showing any reduction in performance Repeated thawing and freezing gt 2 x should be avoided as this may reduce the sensitivity If the reagents are to be used only intermittently they should be frozen in aliquots General Precautions The user should exercise the following precautions while using the kit e Use sterile pipette tips with filters e Store and extract positive material specimens controls and amplicons separately from all other reagents and add it to the reaction mix in a spatially separated facility e Thaw all components thoroughly at room temperature before starting an assay e When thawed mix the components and centrifuge briefly e Work quickly on ice Quality Control In accordance with Norgen s ISO 9001 and ISO 13485 certified Quality Management System each lot of Norgen s VZV 2X PCR Master Mix Control 2X PCR Master Mix Isolation Control IsoC and VZV Positive Control PosC are tested against predetermined specifications to ensure consistent product quality Product Use Limitations Norgen s Plasma Serum VZV PCR Detection Kit is designed for research purposes only It is not intended for human or diagnostic use Product Warranty and Satisfaction Guarantee NORGEN BIOTEK CORPORATION guarantees the performance of all products in the manner described in our product manual The customer must determine the
