Product Description |
Monomethyl auristatin E (MMAE) is a synthetic antineoplastic
agent. It inhibits cell division by blocking the polymerisation of tubulin.It is linked to a monoclonal antibody as a payload in MMAE
conjugated antibody drug (MMAE-ADC) development
[1-3]. There are several FDA approved MMAE-ADC drugs, such as Disitamab
vedotin, Tivdak, Padcev, Polivy and Adcetris. MMAE-ADC can activate
the antimitotic mechanism by cathepsin cleavage after it has entered a tumor
cell, thus [4]. GenScript has comprehensively developed and
validated the MMAE ADC
Pharmacokinetic ELISA Kit for the quantitative measurement of MMAE-ADC in
cynomolgus monkey serum and plasma. This kit is based
on the ICH M10 and the FDA bioanalytical method validation
guidance for industry, ensuring its precision, accuracy, dilutional
linearity, specificity, selectivity, stability, and hook effect were acceptable
[5-8]. The ELISA kit is a validated tool for MMAE-ADC quantification
in biological matrices for drug research and development. |

Assay Principle |
MMAE ADC Pharmacokinetic ELISA Kit is a
sandwich ELISA assay that utilizes an anti-MMAE monoclonal antibody as the capture antibody and an anti-human IgG monoclonal
antibody as the detection antibody. When standards or samples are added to the
capture plate, the anti-MMAE monoclonal antibody coating on the plate can
capture the MMAE-ADC present in the sample. Then the Horseradish Peroxidase
(HRP) conjugated Anti-human IgG monoclonal antibody is added to interact with the MMAE-ADC bound on the plate. After the washing
steps, 3,3',5,5'-Tetramethylbenzidine solution (TMB Solution) is added, resulting
in the formation of blue color. The reaction is stopped by adding Stop Solution.
Adding the Stop Solution changes the color from blue to yellow. The intensity
of the color can be read at 450 nm and 630 nm by a microplate reader. The
quantity of MMAE-ADC in the sample is accurately determined against a MMAE-ADC standard curve. |
