Flow Cytometry
Flow cytometry is a laser-based technology that rapidly measures physical and chemical properties of individual cells or particles in a fluid stream.
Molecular biology techniquesYeast Two-Hybrid System
The yeast two-hybrid system detects protein-protein interactions in living yeast cells by reconstituting a functional transcription factor.
Molecular biology techniquesHeme Biosynthesis and Degradation
Heme is an iron-containing porphyrin that serves as the prosthetic group for hemoglobin, myoglobin, cytochromes, and other essential proteins.
Nucleotide metabolismNucleotide Analogs as Drugs
Nucleotide analogs are a major class of therapeutic agents that interfere with nucleic acid synthesis, used extensively in cancer and antiviral therapy.
Nucleotide metabolismPurine Metabolism
Purine metabolism encompasses the de novo synthesis, salvage, and degradation of purine nucleotides, which are essential for nucleic acids, energy transfer, and signaling.
Nucleotide metabolismPyrimidine Metabolism
Pyrimidine metabolism covers the de novo synthesis, salvage, and degradation of pyrimidine nucleotides including uracil, cytosine, and thymine.
Nucleotide metabolismPCR Applications and Variants
The polymerase chain reaction has spawned numerous specialized variants and applications that extend its utility beyond simple DNA amplification.
PCRAntibody Structure and Function
Antibodies are Y-shaped glycoproteins produced by B cells that recognize and neutralize pathogens through specific antigen-binding sites.
ProteinsProtein Degradation
Protein degradation is a highly regulated process that removes damaged, misfolded, or unneeded proteins through the ubiquitin-proteasome system and autophagy.
