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 22C11 is a ZooMAb® mouse recombinant monoclonal antibody that detects Amyloid precursor A4 protein. It targets an epitope within 16 amino acids from the N-terminal region.

Immunogen

Recombinant bacterial expressed APP A4 (pre A4(695)) fusion protein.

Target description

Amyloid-beta A4 protein (UniProt: P05067; also known as ABPP, APPI, APP, Alzheimer disease amyloid protein, Amyloid precursor protein, Amyloid-beta precursor protein, Cerebral vascular amyloid peptide, CVAP, PreA4, Protease nexin-II, PN-II) is encoded by the APP (also known as A4, AD1) gene (Gene ID: 351) in human. Deposition of Aβ peptides is an early event in the pathogenesis of Alzheimer s disease (AD) that precedes the formation of Tau-positive paired helical filaments (PHFs) in NFTs. AD is also characterized by a progressive deposition of the Aβ peptide in senile plaques. Aβ peptides originate from the proteolytic cleavage of the amyloid precursor protein (APP). Processing of APP occurs by two major pathways cleavage of APP by -secretase is a non-amyloidogenic pathway and does not produce Aβ peptides. Cleavage of APP at the N-terminus of the Aβ region by β-secretase and at the C-terminus by g-secretase represents the amyloidogenic pathway. The β-secretase cleaves APP between residues Met671 and Asp672 and yields sAPPβ and C99. Following the β-secretase cleavage, a second cleavage occurs at the C-terminus of Aβ peptide that releases Aβ from C99. This cleavage occurs in the vicinity of residue 712 of the C-terminus. The -secretase can cleave the C-terminal region at either Val711 or Ile713 to produce the shorter Aβ peptide (Aβ1-40) or the longer Aβ peptide (Aβ1-42), respectively. The predominant form of Aβ found in the cerebrospinal fluid is the shorter Aβ1-40 peptide. Despite its lower rate of synthesis, Aβ1-42 is the peptide that is initially deposited within the extracellular plaques of AD patients. In addition, Aβ1-42 is more hydrophobic and aggregates at much lower concentration than the Aβ1-40 form. The abnormal accumulation of Aβ peptides can result in neuronal damage and loss by increasing free radical production and activation of inflammatory pathways by enhancing microglial secretion of inflammatory cytokines. Interaction between Aβ and ApoE3 or E4 is also an important determinant of amyloidosis. ApoE3 is shown to inhibit Aβ aggregation in vitro by decreasing Aβ multimers, whereas ApoE4 is reported to accelerate the rate of amyloid fibril formation. 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 mouse 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.

Reconstitution

30 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.
