Anti-Cyclophilin B Antibody, clone 4D5 ZooMAb^® Rabbit Monoclonal

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.

Peptidyl-prolyl cis-trans isomerase B (UniProt: P23284; also known as EC:5.2.1.8, PPIase B, CYP-S1, Cyclophilin B, Rotamase B, S-cyclophilin, SCYLP) is encoded by the CYPB (also known as PPIB) gene (Gene ID: 5479) in human. Cyclophilins are a group of peptidyl-prolyl cis/trans isomerases that play crucial role in regulatory mechanisms of cellular physiology and pathology in several inflammatory conditions. Cyclophilin B (CypB) is an endoplasmic reticulum (ER) resident protein that is synthesized with a signal peptide (aa 1-33), which is subsequently cleaved off to produce mature active protein (aa 34-216). It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and therefore assists in protein folding. CypB is secreted by several cell types, and it possesses proinflammatory properties. It is reported to play a key role in ER redox homeostasis. Higher levels of CypB are observed in inflammatory processes, like sepsis and rheumatoid arthritis. It also promotes platelet adhesion to collagen and the neutrophil chemotaxis. It binds to the CD147 membrane receptor to modulate inflammatory pathways. CypB is reported to provide essential survival signals in glioblastoma multiforme cells. Suppression of CypB is shown to reduce the proliferation of glioblastoma cells. Depletion or pharmacological inhibition of CypB causes hyperactivation of the oncogenic RAS-mitogen-activated protein kinase pathway, induction of cellular senescence signals, and death resulting from loss of MYC, mutant p53, Chk1, and JAK/STAT3 signaling. Mutations in CYPB gene are known to cause Osteogenesis imperfecta, a disease characterized by low bone mass, bone fragility and increased susceptibility to fractures even after minimal trauma. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

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.

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.

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.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
