Source
Monoclonal Anti-Adalimumab Antibody, Mouse IgG1 (AY19) (Cat. No. ADB-Y19) is a mouse monoclonal antibody produced from a hybridoma generated by fusion of SP2/0 myeloma cells with mouse B lymphocytes.
Antibody Type
Hybridoma Monoclonal
Clone
AY19
Isotype
Mouse IgG1, Kappa
Host Species
Mouse
Immunogen
Adalimumab
Specificity
AY19 is an inhibitory anti-idiotype monoclonal antibody that specifically recognizes Adalimumab. No detectable binding to the tested human IgG1 controls, TNF-alpha, Trastuzumab, or Bevacizumab was observed under the tested conditions. AY19 inhibits the binding of Adalimumab to TNF-alpha.

Performance Data
Bioactivity-ELISA
Monoclonal Anti-Adalimumab Antibody, Mouse IgG1 (AY19) (Cat. No. ADB-Y19) was evaluated as a surrogate positive control in a bridging ELISA for anti-Adalimumab ADA detection. Adalimumab was immobilized at 1 μg/mL. Increasing concentrations of AY19 prepared in 10% human serum were added, followed by biotinylated Adalimumab at 5 μg/mL. Detection was performed using HRP-conjugated streptavidin (QC tested).
Protocol
The specificity of Monoclonal Anti-Adalimumab Antibody, Mouse IgG1 (AY19) (Cat. No. ADB-Y19) was evaluated by ELISA. Adalimumab was immobilized at 1 μg/mL (100 μL/well). AY19 specifically recognized Adalimumab, with no detectable binding to the tested human IgG1 controls, TNF-alpha, trastuzumab, or bevacizumab under the tested conditions (Routinely tested).
Protocol
The ability of Monoclonal Anti-Adalimumab Antibody, Mouse IgG1 (AY19) (Cat. No. ADB-Y19) to block Adalimumab to TNF-alpha was evaluated by ELISA. Adalimumab was immobilized at 0.5 μg/mL (100 μL/well). Increasing concentrations of AY19 were tested for their ability to inhibit the biotinylated human TNF-alpha to Adalimumab. AY19 inhibited Adalimumab binding to TNF-alpha in a dose-dependent manner, with an IC₅₀ of approximately 0.09 μg/mL under the tested conditions (Routinely tested).
Protocol
Bioactivity-SPR
The binding affinity of Monoclonal Anti-Adalimumab Antibody, Mouse IgG1 (AY19) (Cat. No. ADB-Y19) to Adalimumab was determined by surface plasmon resonance (SPR). AY19 was captured on an anti-mouse IgG-coupled CM5 sensor chip, and Adalimumab was injected as the analyte at serial concentrations (0.039-5 nM). The apparent equilibrium dissociation constant (KD) was determined to be 1.36E-12 M (1.36 pM).

FAQ

Can lyophilized proteins remain stable during room-temperature shipping or temporary room-temperature exposure?
In general, lyophilized proteins remain stable during room-temperature shipping or temporary exposure to room-temperature conditions.
Many ACROBiosystems recombinant proteins are supplied in lyophilized (freeze-dried) form. The lyophilization process effectively removes moisture from the product, helping reduce degradation-related reactions and improve protein stability during transportation and storage.
To evaluate the stability of lyophilized proteins under normal temperature conditions, ACROBiosystems conducted a stability study on 11 representative lyophilized protein products at 37°C. The study demonstrated that these proteins maintained good quality stability after storage at 37°C for approximately 20 days. Based on these validation results, temporary room-temperature exposure during shipping or handling is generally not expected to have a significant impact on product quality or downstream application performance.
To ensure optimal long-term stability, products should be stored according to the storage conditions specified in the product Certificate of Analysis (COA) upon receipt.
