MtoZ Biolabs’ Mouse Immunoglobulin G (IgG) ELISA Kit accurately quantify mouse IgG in serum, plasma, cell culture supernatants, and other biological fluids. This sandwich ELISA kit delivers high sensitivity and reproducibility for immunology research, antibody production monitoring, and preclinical studies.
Product Overview
Accurate quantification of mouse IgG involves multiple analytical hurdles — from subclass structural variation to complex sample matrices, each factor can significantly impact assay performance:
1. Uneven Subclass Coverage
Mouse IgG comprises four subclasses (IgG1, IgG2a, IgG2b, IgG3) with notable structural differences. Conventional antibodies often fail to capture all subclasses equally, leading to quantification bias.
2. Non-Specific Interference
Heterophilic antibodies and rheumatoid factors present in samples can bind non-specifically to detection antibodies, resulting in false positives or inflated readings.
3. Hook Effect Risk
Serum IgG concentrations can reach several mg/mL. Insufficient sample dilution triggers the hook effect, causing signal suppression at high analyte concentrations.
4. Complex Matrix Effects
Diverse sample types carry varying background components that affect standard curve fitting and recovery rates.
5. Cross-Reactivity with Other Immunoglobulins
Structural similarities between IgG and other isotypes such as IgM and IgA can cause cross-reactivity when antibody selectivity is insufficient.
6. Low-Abundance Sample Challenges
IgG levels in cell culture supernatants and similar samples are extremely low, placing high demands on kit sensitivity and signal-to-noise ratio.
Advantages
✅ High Sensitivity
Detection range as low as ng/mL; ideal for low-abundance samples.

✅ Minimal Cross-Reactivity
No interference with IgM, IgA, or IgE.
✅ Optimized Matrix Compatibility
Validated in serum, plasma, and cell culture supernatant.
✅ Ready-to-Use Format
Pre-coated plates and lyophilized standards included.
