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.

Specificity

Clone 1A11 is a ZooMAb rabbit recombinant monoclonal antibody that detects Calbindin. It targets an epitope with in the C-terminal half.

Immunogen

GST/His-tagged recombinant fragment corresponding to 107 amino acids from the C-terminal half of murine Calbindin.

Application

Anti-Calbindin D-28K, clone 1A11, ZooMAb, Cat. No. ZRB1778, is a recombinant Rabbit Monoclonal Antibody that detects Calbindin D-28K and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Calbindin D-28K in mouse brain tissue lysate.

Immunohistochemistry (Paraffin) Analysis: A 1:400 dilution from a representative lot detected Calbindin D-28K in mouse kidney tissue sections.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Calbindin D-28K in PC12 cells.

Target description

Calbindin (UniProt: P12658; also known as Calbindin D28, D-28K, PCD-29, Spot 35 protein, Vitamin D-dependent calcium-binding protein, avian-type) is encoded by the calb1 gene (gene ID: 12307) in murine species. Calbindin D-28k is a member of a large family of intracellular calcium-binding proteins of the EF-hand related to calmodulin and troponin-C. Calbindin D-28K has four functional calcium-binding sites (aa 24-35; 111-122; 155-166; and 199-210). It has moderate cytoplasmic mobility and comprises six EF-hands, of which one or two are non-functioning in metal binding. EF-2 is viewed as non-metal binding and EF-6 may have a very low Ca2+ affinity. Four EF hands function in calcium binding with rapid to intermediate kinetics and affinity. The biological roles of Calbindin D-28K include calcium regulation and signaling, including calcium transport and uptake, calcification of bone and teeth, and calcium related signaling in neurons and transiently in embryological development. It also protects neurons from apoptotic cell death. Decline in Calbindin D-28K levels in hippocampal dentate granule cells correlates with the kindling model for epilepsy. Calbindin D-28K immunoreactivity is shown to be specifically absent from neuronal populations lost early in ALS, while substantial loss of neurons, which do contain this protein occur in patients with Huntington′s disease. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Schmidt, H (2012). Front. Mol. Neurosci. 5; 25).

Physical form

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

Reconstitution

120 μg/mL after reconstitution at 25 μL. 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.
