Specificity: This non-therapeutic biosimilar antibody uses the same variable region sequence as the therapeutic antibody Ipilimumab. Ipilimumab binds to Human CTLA-4. This product is for research use only.
Endotoxin Level: ≤ 1.0 EU/mg as determined by the LAL method. Purity: ≥95% monomer by analytical SEC.
Product Preparation: Functional grade preclinical antibodies are manufactured in an animal free facility using only In vitro protein 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 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.
This antibody has been tested in the following applications: Flow Cytometry, ELISA, CyTOF® Blocking.
CTLA4 (Cytotoxic T-Lymphocyte Antigen 4) is a CD28-family receptor expressed on mainly CD4+ T cells. It binds the same ligands as CD28 (CD80 and CD86 on B cells and dendritic cells), but with higher affinity than CD28. However, in contrast to CD28 which enhances cell function when bound at the same time as the T cell receptor, CTLA4 inhbits the T cell and prevents it from functioning. Intracellular CTLA4 is also found in regulatory T cells and may be important to their function.
