Quinolinic Acid Monoclonal Antibody

The Quinolinic Acid Monoclonal Antibody is For Research Use Only

Synonyms:  Pyridine-2,3-dicarboxylic acid antibody, 2,3-pyridinedicarboxylic acid antibody,  3,4-Pyridinedicarboxylic acid,  antibody Pyridine-3,4-dicarboxylic acid antibody

Immunogen:  Conjugated quinolinic acid Isotype:  IgG1 k chain

Clone:   Clone 4E11-G3

Specificity:  When tested in competitive ELISA, the anti-Quinolinic acid antibody did not show any significant cross reactivity with Picolinic and Quinaldic acid conjugates.

Concentration:  0.5 mg/mL

Size:  50 µL

Storage:  4°C

Affinity & Specificity
Competitive ELISA demonstrates that low amounts of Quinolinic acid conjugate are required to abolish antigen-antibody reaction (high affinity), while rising concentrations of Picolinic and Quinaldic acid conjugates do not affect the reaction (high specificity).

Immunohistochemistry (IHC): Dilute at 1:100-1:1000. Perform heat antigen retrieval (pH=9) before initiating IHC staining protocol on paraffin-embedded and frozen sections
Immunofluorescence (IF): Dilute at 1:50-1:500 on paraffin-embedded and frozen sections. Perform heat antigen retrieval and incubate fluorescent dyes conjugated secondary antibody
Comments: Optimal working dilutions must be determined by the end-user
