The Essential Role of Secondary Antibodies in Immunoassays: Structure, Selection, & Applications
Key Takeaways
Core role & benefit of secondary antibodies
Key structural elements
Crucial selection rules
Types and labels
Applications
Future enhancementsPrimary antibodies – first line of detection in immunoassays,
and bind specifically to a target antigen (a protein, peptide, or other
biomolecule).
What are secondary antibodies?
Secondary antibodies are labeled with markers (like an enzyme,
dye, or fluorescent tag)....

What Are Phospho Antibodies?
Phosphorylation is when a phosphate group is added to a protein. It usually
happens on specific amino acids comprising the protein – specifically, serine,
threonine, or tyrosine – and is performed by specialized enzymes called kinases.
Phosphorylation helps to “turn on” or control important processes in cells.
Phospho-specific antibodies are special tools, primarily made...

Recombinant Antibody Overview: Production & Applications
An Overview
Recombinant antibodies are lab-made alternatives to traditional monoclonal
antibodies. No animals are used in their production.
Allow for high batch-to-batch consistency, scalability, and customization.
Ideal for research and diagnostics.
Types of recombinant antibodies include chimeric antibodies and smaller
fragments like scFv, Fab, and VHH.
These antibodies are engineered for better tissue penetration. There will be
shorter...

What Are Antibodies: Structure, Function & Types
An antibody is a protein that helps protect the body
internally.
Key Takeaways
Antibodies are proteins that defend the body against harmful invaders.
Each B cell makes antibodies for one specific antigen.
Antibodies recognize and bind to antigens (the vast majority of which are
“foreign”) and help remove them.
Antibody structure is Y-shaped with two antigen-binding sites.
Five...

What Are Monoclonal Antibodies (MABs): Their Uses, Types & Benefits
Key Takeaways
Monoclonal antibodies (mAbs) are lab-made proteins.
They are very precise in their targeting of harmful substances like viruses, bacteria, and cancer cells.
There are four main types of mAbs based on their origin: murine (mouse),...

What Are Polyclonal Antibodies and Why Do They Matter?
When the body’s immune system detects the presence of something “foreign”, like bacteria or viruses (called antigens), it activates, and produces various responses. This includes activation of certain immune cells called B cells, which begin making special proteins known as antibodies.
Polyclonal antibodies are a mix of different antibodies...
