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.


Clone 2E18 is a ZooMAb® rabbit recombinant monoclonal antibody that specifically detects Calcitonin gene-related peptide 1. It targets an epitope within 22 amino acids from the active form of CGRP1.


KLH-conjugated linear peptide corresponding to 22 amino acids from human active Calcitonin gene-related peptide 1 (C-terminal region of the uncleaved peptide)


Quality Control Testing

Evaluated by Western Blotting in MCF-7 cell lysate.

Western Blotting Analysis: A 1:1,000 dilution of this antibody detected Calcitonin Gene-Related Peptide 1 (CGRP-1) in MCF-7 cell lysate.

Tested Applications

Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected CGRP-1 in PC12 and K562 cells and in Human and mouse liver lysates.

Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected CGRP-1 in human cerebral cortex and human DRG tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound CGRP-1 peptide with a KD of 1.9 x 10-7 in an affinity binding assay.

Immunocytochemistry Analysis: A 1:1,000 dilution from a representative lot detected CGRP-1 in MCF7 cells.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-CGRP-1, clone 2E18 ZooMAb®, Cat. No. ZRB1267, is a recombinant Rabbit monoclonal antibody that specifically targets CGRP-1 and is tested for use in Affinity Binding Assay, Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.

Target description

Calcitonin gene-related peptide 1 (UniProt: P06881; also known as Alpha-type CGRP, Calcitonin gene-related peptide I, CGRP-I) is encoded by the CALCA (also known as CALC1) gene (Gene ID: 746) in human. CGRP, a 37 amino acid neuropeptide, is a highly potent and long-acting vasodilator with protective effects in the cardiovascular system. Two forms of CGRP have been described -CGRP-I and CGRP-II (also known as aCGRP and bCGRP) that are synthesized from two distinct genes. CGRP I is the primary neuronal form that is found in the CNS and in the peripheral nervous system and displays higher immunoreactivity than CGRP II. CGRP I is synthesized with a signal peptide (aa 1-25) and two peptides (aa 26-80 and 125-128) that are cleaved off to generate biologically active form (aa 83-119). Following synthesis, it is stored in large, dense-core vesicles within the sensory nerve terminal and is released following neuronal depolarization via calcium-dependent exocytosis. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Russell, FA., et al. (2014). Physiol. Rev. 94(4): 1099-1142).

Physical form

Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. 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.
