Target description

Receptor-interacting serine/threonine-protein kinase 1 (UniProt: Q13546; also known as EC:, Cell death protein RIP, Receptor-interacting protein 1, RIP-1, RIPK1) is encoded by the RIPK1 (also known as RIP, RIP1) gene (Gene ID: 8737) in human. RIPK1 is a serine-threonine kinase that serves as a key regulator of TNF-a-mediated apoptosis, necroptosis, and inflammatory pathways. It exhibits kinase activity-dependent functions that regulates cell death and kinase-independent scaffold functions that regulate inflammatory signal transduction and cell survival. Upon binding of TNF-a to TNFR1, RIPK1 is recruited to the TNF-R1 signal transduction complex where it acts as a scaffold protein promoting cell survival, in part, by activating the canonical NF-kB pathway. RIPK1 is required to limit caspase 8-dependent TNFR1-induced apoptosis. Under normal conditions, RIPK1 acts as an inhibitor of RIPK3-dependent necroptosis via FADD-mediated recruitment of caspase 8, which cleaves RIPK1 (at Asp 324) and limits TNF-a-induced necroptosis. It is also required to inhibit apoptosis and necroptosis during embryonic development where it acts by preventing the interaction of TRADD with FADD thereby limiting aberrant activation of caspase 8. In addition to apoptosis and necroptosis, it is also involved in inflammatory response by promoting transcriptional production of pro-inflammatory cytokines. RIPK1 and RIPK3 are known to undergo reciprocal auto- and trans-phosphorylation. Phosphorylation of RIPK1 at Ser 161 by RIPK3 is crucial for the formation of the necroptosis-inducing complex. Its phosphorylation at Ser 25 represses its kinase activity and consequently prevents TNF-a-mediated RIPK1-dependent cell death. This ZooMAbZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
