To determine the IgG isotype of neutralizing anti-drug antibodies, ELISAs were performed as follows. 96-well Maxisorp ELISA plates (Thermo Scientific) were coated overnight at 4°C with 50 ng agalsidase-alfa, washed 3x with PBS, and blocked for 2h at RT with 100 µl PBS/BSA 2% (per well). Subsequently, wells were washed 5x with PBS/Tween 0.1%. Purified total IgGs from patients) were used as primary antibodies and were applied in serial dilutions (1:250 1:500 1:1,000) in PBS/BSA 2% overnight at 4°C. Next day, cells were washed again 5x PBS/Tween 0.1% and incubated for 1 h at RT with IgG isotype-specific anti-human IgG-HRP (mouse α-human IgG isotype 1 [ab99774] mouse α-human IgG isotype 2 [ab99779] rabbit α-human IgG isotype 3 [ab86253] mouse α-human IgG isotype 4 [ab99823] goat α-human IgA [ab97215] mouse α-human IgE [ab99806]). Rabbit α-human IgG isotype 3 was detected with goat α-rabbit IgG-HRP [sc-2054, Santa Cruz Biotechnology,] as secondary antibody (diluted 1:5,000).
After 5 additional washes, 100 µl 1-Step Ultra TMB-ELISA Substrate Solution (Thermo Scientific) was added to each well, incubated for 10 min, and stopped with 2M sulfuric acid. The absorption was measured at 450 nm and ratios were calculated between Enzyme replacment therapy-naïve and -treated status.

Thank you for your inquiry.

The concentration is lot specific of these antibodies and will not be written on the bottle. I am however very happy to check this for you - I am currently checking the concentrations of the lots we are having in stock.

If you have not yet received the antibodies, I can check the concentrations of the current lot. If you have already ordered the antibodies, please provide me with the lot numbers of the antibodies you have, and I will check the concentration with the laboratory for the respective antibodies.

If you do not have the lot numbers, please provide me with the order information, so I can trace back the lot numbers myself.

I look forward to hear back from you.

Following on my previous message about the secondary antibodies you are interested in, the anti-human IgG isotypes are tested on a Human IgG subclass plate (IgG1, IgG2, IgG3, and IgG4) to ensure activity and minimal cross reactivity with the other IgG subclasses.
