Gradient PCR is not an actual type of PCR. It is a variant of the conventional PCR that makes it easier to optimize PCR reactions by pinpointing the precise annealing temperature. The PCR allows for the amplification of an infinite number of amplicons, or copies of the gene of interest, which are

Nucleic acid extraction and purification is the primary step for the downstream applications like sequencing, RT-PCR amplification, hybridization, cloning and biological detection. It is critical to ensure reliable results in molecular diagnostic tests and molecular biology research. This article elaborates the popular extraction methods and discusses the merits and shortfalls of each.

Outlines key factors to consider before selecting a Laboratory centrifuge including Centrifuge Speed or RPM/RCF Range, Rotor Capacity & Type, Cooling requirement, Safety features etc., and lists the main types of centrifuges available commercially.

COVID-19 Nucleic Acid RT-PCR Testing: Sample Preparation Tools. Four E's Scientific offers tools required for SARS-Cov-2 Nucleic Acid Amplification Tests (NAAT), a real-time RT-PCR test intended for the qualitative detection of RNA from the SARS-CoV-2 virus in upper respiratory specimens.

Tips for Pipette MaintenanceThe pipette is a commonly used scientific instrument in biological and chemical laboratories. It’s essential to know how to use it correctly. Equally important, pipettes need regular maintenance to ensure reliable results and longer service life. Typically, preventative m
