Residual host cell DNA refers to fragments of DNA from the host organism that are left behind after a biological process such as the production of a biopharmaceutical product or the cultivation of a cell line. This residual DNA can potentially contaminate the final product and affect its safety and efficacy.In the context of biopharmaceutical production regulatory agencies such as the FDA and EMA have set limits on the amount of residual host cell DNA that is acceptable in a final product. These limits vary depending on the type of product and the route of administration and residue host cell DNA quantitative kits are designed to ensure that the final product is safe for human use.

Human IgG4 (S108P) Kappa Isotype Control (mAb) is a chimeric monoclonal antibody recombinantly expressed from human 293 cells (HEK293) which combines the variable region of a mouse monoclonal antibody with human IgG1 constant domain. The mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with DNP.

Defibrinated chicken blood is aseptically collected and prepared to order from our colony of animals. Fibrin is mechanically removed during the clotting process without the presence of anticoagulants or other additives. Defibrinated chicken blood is ideal for blood agar plate preparations. Blood Agar is a general purpose enriched medium often used to grow fastidious organisms and to differentiate bacteria based on their hemolytic properties. Defibrinated chicken blood is perishable and is collected and processed upon receipt of your order.

TNF-like cytokine 1A (TL1A) and its receptors death receptor 3 (DR3) and decoy receptor 3 (DcR3) are members of the TNF and TNF receptor superfamilies of proteins respectively. Binding of APC-derived TL1A to lymphocytic DR3 provides co-stimulatory signals for activated lymphocytes. DR3 signaling affects not only the proliferative activity of and cytokine production by effector lymphocytes but also critically influences the development and suppressive function of regulatory T-cells. Whereas DcR3 restricts the function of the TL1A/DR3 complex: attenuating T-cell activation and downregulating the secretion of pro-inflammatory cytokines. Together with DR3 and DcR3 TL1A constitutes a cytokine system that actively interferes with the regulation of immune responses.
