Host species
Match Mouse, Rat, Rabbit, Human or another host to the experimental antibody.
ISOTYPE CONTROL ANTIBODIES
Isotype Control Antibodies
Controls for assessing nonspecific binding and background, matched by host species, Ig subclass, light chain and fluorophore.
MATCHING CRITERIA
Match the experimental antibody attribute by attribute
Where possible, an isotype control should match the experimental antibody's host, immunoglobulin class, light chain, label and use conditions.
Ig class and subclass
Match immunoglobulin class and subclass, such as IgG1, IgG2a, IgG2b or IgM.
Light-chain type
When known, match κ or λ to reduce molecular-background differences.
Fluorophore
For directly labeled antibodies, prefer the same fluorophore and compare at similar concentration and test amount.
SELECTION SUPPORT
Coordinate with flow antibodies and labeling services
Provide the experimental antibody's host, Ig subclass, light chain, fluorophore, concentration and planned amount so the technical team can review matching criteria. Structured product master data are not yet available for this category, so unconfirmed catalog numbers, inventory or performance parameters are not shown.
- Labeled experimental antibody: prefer the same fluorophore
- Multicolor flow: plan alongside single-stain, FMO and other controls
- Out-of-catalog combination: assess custom fluorescent labeling and basic quality checks
