Vector Laboratories supports your protein research by offering a wide range of reagents and kits for protein detection and analysis on western blots.
Label antibodies with biotin (for avidin/streptavidin-based detection), peroxidase (HRP; for enzymatic, chromogenic detection), or fluorescent compounds (for fluorescence detection). The choice of label depends on many factors, including the sensitivity desired and instrumentation available for detection. Vector offers a variety of reagents and kits for protein labeling, as well as a wide range of prelabeled secondary antibodies (see Detection).
Protein Labeling
Purify labeled antibodies and proteins using affinity chromatography with agarose-immobilized, Ig- or biotin-specific reagents.
Affinity Binding Matrices Biotin Quantitation
Prior to immunological detection, block unoccupied binding sites on the blot to prevent nonspecific binding of the detection antibodies. Failure to do so can lead to high background.
Endogenous Biotin Blocking Kits Protein Blocking Solutions Western Blot Blocking Solutions
Apply the labeled primary and/or secondary antibodies to the blot to detect the target protein. Choose from avidin/streptavidin-, enzyme-, or fluorescence-based detection methods and kits.
Enzyme Avidin/Streptavidin Fluorophore Avidin/Streptavidin Secondary Antibodies ABC Kits for Western Blot Detection Enzyme Polymers for Western Blot Detection
If using an enzymatic detection method, visualize the labeled antibody with an appropriate substrate for chromogenic or chemiluminescent/ chemifluorescent detection.
