Antigen Distribution:PD-1 is expressed on activated T cells, B cells, a subset of thymocytes, macrophages, dendritic cells, and some tumor cells and is also retained in the intracellular compartments of regulatory T cells (Tregs).
Formulation:This biosimilar antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.
Specificity:Spartalizumab activity is directed against human PD-1.
Additional Applications Reported In Literature:ELISA WB IP FA FC

PD-1 is a transmembrane protein in the CD28/CTLA-4 subfamily of the Ig superfamily 1, 2 . When stimulated via the T cell receptor (TCR), Tregs translocate PD-1 to the cell surface 3. Programmed cell death 1 ligand 1 (PD-L1; CD274; B7H1) and programmed cell death 1 ligand 2 (PD-L2; CD273; B7DC) have been identified as PD-1 ligands 1. PD-1 is co-expressed with PD-L1 on tumor cells and tumor-infiltrating antigen-presenting cells (APCs) 2 . Additionally, PD-1 is co-expressed with IL2RA on activated CD4 + T cells 3 .

PD-1 is an immune checkpoint receptor that suppresses cancer-specific immune responses 4. Additionally, PD-1 acts as a T cell inhibitory receptor and plays a critical role in peripheral tolerance induction and autoimmune disease prevention as well as important roles in the survival of dendritic cells, macrophage phagocytosis, and tumor cell glycolysis 2. PD-1 prevents uncontrolled T cell activity, leading to attenuation of T cell proliferation, cytokine production, and cytolytic activities. Additionally, the PD-1 pathway is a major mechanism of tumor immune evasion, and, as such, PD-1 is a target of cancer immunotherapy 2.

Spartalizumab is a humanized IgG4 anti-PD1 antibody that has been tested for thetreatment of various cancers 5, 6. Spartalizumab binds PD-1 with sub-nanomolar affinity and blocks interactions with ligands PD-L1 and PD-L2, leading to T cell activation 5.

Ligand/Receptor:PD-L1, CD274
State of Matter:Liquid
Regulatory Status:Research Use Only
Product Preparation:Recombinant biosimilar antibodies are manufactured in an animal free facility using onlyin vitroprotein free cell culture techniques and are purified by a multi-step process including the use of protein A or G to assure extremely low levels of endotoxins, leachable protein A or aggregates.
Pathogen Testing:To protect mouse colonies from infection by pathogens and to assure that experimental preclinical data is not affected by such pathogens, all of Leinco’s recombinant biosimilar antibodies are tested and guaranteed to be negative for all pathogens in the IDEXX IMPACT I Mouse Profile.
Storage and Handling:Functional grade biosimilar antibodies may be stored sterile as received at 2-8°C for up to one month. For longer term storage, aseptically aliquot in working volumes without diluting and store at -80°C.Avoid Repeated Freeze Thaw Cycles.
