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 1D2 is a Rabbit recombinant monoclonal antibody that detects Red/Green opsin. It targets an epitope within 19 amino acids from the first extracellular domain within the N-terminal region.

KLH-conjugated linear peptide corresponding to a sequence of 19 amino acids from the N-terminal, extracellular domain that is common to human Red and Green opsin 1.

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.

Long-wave-sensitive opsin 1/Medium-wave-sensitive opsin 1 (UniProt: P04000/P04001; also known as Red cone photoreceptor pigment/Green cone photoreceptor pigment, Red-sensitive opsin/ Green-sensitive opsin, ROP/GOP) are encoded by the OPN1LW/OPN1MW (also known as RCP/GCP) genes (Gene ID: 5956/2652) in human. The full range of color discrimination in humans is based on the presence and function of three cone photoreceptors. Each cone type possesses a photo-sensitive pigment-protein complex consisting of 11-cis retinal and a unique opsin protein that gives sensitivity in the short (S cone, peak sensitivity about 420 nm), middle (M cone, peak sensitivity about 530 nm with polymorphism), and long (L cone, peak sensitivity about 560 nm with polymorphism) wavelengths of the light spectrum. Opsins are multi-pass membrane proteins that belongs to the G-protein coupled receptor 1 family. They consist of four extracellular, 7 helical, and four cytoplasmic domains. Genes for the three types of cone opsins and the rod photoreceptor rhodopsin gene seem to be homologous with varying amounts of conservation. Strongest conservation is between the middle (green) and long (red) wavelength sensitive pigments on the X chromosome, suggesting a relatively recent duplication/divergence event. The S cone (blue) opsin seems to have a stronger conservation with rhodopsin. Cone photoreceptor distribution in humans is dominated by the M and L cone pigments. Mutations in OPN1MW and OPN1LW genes are known to cause color blindness that is characterized by a dichromasy in which red and green are confused, without loss of luminance or shift or shortening of the spectrum. Some mutations also lead to cone dystrophy leading to progressive degeneration of the cone photoreceptor with some preservation of rod function. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Recommend storage of lyophilized product at 2-8℃; 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℃, or -20℃ for long term storage. Avoid repeated freeze-thaws.
