MRD Analysis of the Detection of Mosunetuzumab or Cevostamab in Biological Matrix.
The MRD is the minimum dilution necessary for the detection of Mosunetuzumab or Cevostamab in biological matrix with least interference. Serum samples from cynomolgus monkey were serially diluted to determine the MRD of this assay, and the test result suggested that MRD was as 1:25.
In this ELISA assay, MonoRab? Anti-Mosunetuzumab Antibody (4G6), mAb, Rabbit (GenScript, A02290) was coated at a concentration of 1 μg/ml, and MonoRab? Anti-Mosunetuzumab Antibody (38A10), mAb, Rabbit (GenScript, A02291) conjugated with Biotin was used as a detection antibody at a concentration of 0.4 μg/mL.
Specificity analysis of the detection of Mosunetuzumab or Cevostamab.
Mosunetuzumab or Cevostamab samples at 7 concentrations were spiked with 10 μg/mL of human IgG1. The test result demonstrated that the high concentration of human IgG1 did not interfere with the detection of Mosunetuzumab or Cevostamab.
In this ELISA assay, MonoRab? Anti-Mosunetuzumab Antibody (4G6), mAb, Rabbit (GenScript, A02290) was coated at a concentration of 1 μg/ml, and MonoRab? Anti-Mosunetuzumab Antibody (38A10), mAb, Rabbit (GenScript, A02291) conjugated with Biotin was used as a detection antibody at a concentration of 0.4 μg/mL.
