SILu™MAb Infliximab Stable-Isotope Labeled Monoclonal Antibody (MSQC9) is a recombinant, stable isotope-labeled, monoclonal antibody which incorporates [13C6, 15N4]-Arginine and [13C6, 15N2]-Lysine. Expressed in CHO cells, it is designed to be used as an internal standard for the quantitative mass spectrometry analysis of Infliximab in human serum. Infliximab is a chimeric monoclonal antibody biologic drug that works against tumor necrosis factor alpha (TNF-a) and is used to treat autoimmune diseases.
Infliximab has been approved for the treatment of Crohns disease, ulcerative colitis, psoriasis, psoriatic arthritis, ankylosing spondylitis, and rheumatoid arthritis. SILu™MAb Infliximab Stable-Isotope Labeled Monoclonal Antibody is for R&D use only. Not for drug, household, or other uses.

Physical form
Each vial of SILu™Mab Infliximab Stable-Isotope Labeled Monoclonal Antibody contains the labeled antibody in a lyophilized form containing phosphate buffered saline.
Preparation Note
Produced utilizing enriched media containing stable isotope labeled amino acids are 13C6, 15N4-labeled Arginine and 13C6, 15N2-labeled Lysine.
SILu™Mab Infliximab Stable-Isotope Labeled Monoclonal Antibody is designed to be used as a internal standard for analysis of Infliximab in human serum.
Reconstitution
SILu™Mab Infliximab recovery is maximized when 0.1% formic acid is used for reconstitution of the lyophilized product.Reconstitution with other solvents may reduce recovery. Do not freeze after reconstitution.

• Briefly centrifuge the vial at ~10,000 x g to collect the product at the bottom of the vial.
• Add 500 µL of ultrapure water containing 0.1% formic acid to the vial.
• Mix the contents by gently inverting the vial a minimum of 5 times.
• Allow the vial to stand at room temperature for at least 15 minutes and repeat mixing by inversion.
