How to use

In Vitro:

The anti-TNF antibodies blocking the action of TNF alpha revolutionized therapy of TNF-related diseases such as Inflammatory Bowel Disease, lupus, ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and rheumatoid arthritis. By neutralizing TNF activity, anti-TNF antibodies promote mucosal healing and induce long-term remissions in vivo. The main anti-TNF antibodies that are currently authorized encompass Infliximab, Etanercept, Adalimumab, Certolizumab and Golimumab.
