Champion™ pET100 Directional TOPO® Expression Kit with BL21 Star™ (DE3) One Shot® Chemically Competent E. coli

Category: Products & Services > Kits & Assays > Protein Expression Kits > Bacterial Expression Kits

The Champion™ pET Expression System yields the highest-level protein production in E. coli . During expression, your protein of interest can reach levels greater than 50 percent of total cellular protein. Based on T7 expression vectors originally developed by Studier and colleagues (1-3), high-level expression is achieved because the T7 RNA polymerase is more processive than native E. coli RNA polymerase and is dedicated to the transcription of your gene of interest. Protein production is further enhanced in the system by the expression strain BL21 Star™ E. coli , which significantly improves ...

AmpFLSTR® Yfiler® Direct Kit

Category: Products & Services > Kits & Assays > Forensic Testing Kits > Forensic DNA Identification Kits

The AmpFLSTR® Yfiler® Direct Kit enables forensic laboratories to perform high-quality Y-STR analysis of single-source reference samples using direct PCR amplification. This kit amplifies the same 17 Y-STR loci as the AmpFLSTR® Yfiler® Kit and is designed to generate accurate results with faster thermocycling conditions than the Yfiler® Kit. Blood or buccal samples on treated paper (FTA® Card or NUCLEIC-CARD™ System ) can be punched into PCR plates or tubes and taken directly to PCR amplification, without reduction in data quality. Samples collected with the Buccal DNA Collector™ and other unt...
