Bacterial Transformation
Bacterial transformation introduces exogenous plasmid DNA into competent bacterial cells, enabling cloning, protein expression, and library construction.
GuidesCRISPR Screening
CRISPR screening uses pooled single-guide RNA libraries to identify genes essential for a phenotype of interest in a high-throughput, genome-wide manner.
GuidesGateway and TOPO Cloning
Gateway recombinational cloning and TOPO cloning are rapid, PCR-based methods for transferring DNA sequences between plasmids without restriction enzymes or ligase.
GuidesGibson Assembly and Golden Gate Cloning
Gibson Assembly and Golden Gate cloning enable seamless, scarless assembly of multiple DNA fragments in a single reaction for synthetic biology and large construct engineering.
GuidesTransfection Methods
Transfection delivers nucleic acids into eukaryotic cells for studying gene function, protein expression, and genetic manipulation.
GuidesFDA Clears First Over-the-Counter Continuous Glucose Monitor for Children
FDA clears Dexcom's Stelo Glucose Biosensor System as the first over-the-counter continuous glucose monitor for children ages 2 and older who do not use insulin.
NewsBlood Gas Analysis and Serum Protein Electrophoresis
Blood gas analysis assesses respiratory and metabolic acid-base status, while serum protein electrophoresis separates serum proteins for diagnosing monoclonal gammopathies and inflammatory conditions.
GuidesUrinalysis
Urinalysis is a non-invasive diagnostic test that assesses kidney function, metabolic disorders, and urinary tract infections through physical, chemical, and microscopic examination.
GuidesSchlenk Line and Air-Free Techniques
Schlenk line and air-free techniques enable the safe handling of air- and moisture-sensitive compounds using inert gas and vacuum manifold systems.
GuidesColumn Chromatography and Flash Chromatography
Column chromatography separates compounds by differential adsorption to a stationary phase, and flash chromatography accelerates the process with pressurized solvent flow.
GuidesDistillation Techniques
Distillation separates liquid mixtures based on differences in boiling points, with simple, fractional, steam, and vacuum distillation covering different separation challenges.
GuidesRecrystallization and Liquid-Liquid Extraction
Recrystallization purifies solid compounds by selective dissolution and crystallization, while liquid-liquid extraction transfers solutes between immiscible solvents.
