Clone 3L16 is a ZooMAb^® recombinant rabbit monoclonal antibody that specifically detects IL-1 . It targets an epitope within 15 amino acids from the C-terminal half.

Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.

Interleukin-1 alpha (UniProt: P01583; also known as IL-1 alpha, Hematopoietin-1) is encoded by the IL1A (also known as IL1F1) gene (Gene ID: 3552) in human. IL-1 is constitutively expressed in several healthy tissues in a steady state and its expression can be increased in response to a number of stimuli. Absolute amounts of IL-1 vary among cell types, but barrier cells, such as endothelial and epithelial cells, express higher amounts at steady state. IL-1 is synthesized with a propeptide (aa 1-112) and is post-translationally modified by phosphorylation at serine 90, myristoylation on lysine 82, and acetylation on lysine 82. After synthesis, pro-IL-1 is localized into the nucleus, cytosol or lysosomal compartment or is displayed on the outer leaflet of the plasma membrane. Its intracellular localization can change in response to specific stimuli. Pro-IL-1 can also be cleaved by calpain to generate IL-1 -N-terminal domain (NTP) and a mature C-terminal IL-1 form. The C-terminal domain is catalytically active and is capable of signaling via IL-1R. Both IL-1 -NTP and pro-IL-1 contains a functional NLS signal and bind HAX1 to allow translocation into the nucleus. In the nucleus, IL-1 -NTP binds transcription regulation factors and activates expression of proinflammatory cytokines and chemokines independently of IL-1R1 signaling. The biological functions of IL-1 also involve stimulation of thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. This ZooMAb^® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

ZooMAb^® antibodies represent an entirely new generation of recombinant monoclonal antibodies. Each ZooMAb^® antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb^® antibodies are reliably available and ready to ship when you need them.

KLH-conjugated linear peptide corresponding to 15 amino acids from the C-terminal half of human IL-1 .

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 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.

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.
