Look to Tonbo for a wide selection of mouse and human antibodies in our no azide, low endotoxin and carrier-free In Vivo Ready™ (IVR) format. Endotoxin levels less than 0.01 EU/µg of protein means they are ideal for sensitive in vivo or in vitro assays like neutralization, blocking or activation. We are also happy to offer any of our existing clones in IVR format on a custom basis. Need bulk quantities? Ask us for a quote.
