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.

Spezifität

Clone 1C20 is a ZooMAb® Rabbit recombinant monoclonal antibody that detects Lubricin (Proteoglycan 4). It targets an epitope within 24 amino acids from the C-terminal region.

Immunogen

KLH-conjugated linear peptide corresponding to 24 amino acids from the C-terminal region of human Lubricin (Proteoglycan 4).

Anwendung

Quality Control Testing

Evaluated by Western Blotting with recombinant human PRG4 protein.

Western Blotting Analysis: A 1:10,000 dilution of this antibody detected recombinant human Lubricin/PRG4.

Tested Applications


Immunohistochemistry (Paraffin) Analysis: A 1:100 dilution from a representative lot detected Lubricin/PRG4 in mouse cartilage tissue sections.

Affinity Binding Assay: A representative lot of this antibody bound Lubricin/PRG4 with a KD of 1.6 x 10-7 in an affinity binding assay.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user

Zielbeschreibung

Proteoglycan 4 (UniProt: Q92954; also known as Lubricin, Megakaryocyte-stimulating factor, Superficial zone proteoglycan) is encoded by the PRG4 (also known as MSF, SZP) gene (Gene ID: 10216) in human. Proteoglycan 4 is a heavily O-glycosylated, secreted, mucin-like protein that is synthesized with a signal peptide (aa 1-24), which is subsequently cleaved off to generate the mature form (aa 25-1404) that can be further cleaved into a C-terminal part (aa 1307-1404). It is highly expressed in synovial tissue, cartilage, and liver and is weakly expressed in heart and lung. It is reported to play a role in boundary lubrication within articulating joints and prevents protein deposition onto cartilage from synovial fluid by controlling adhesion-dependent synovial growth and inhibiting the adhesion of synovial cells to the cartilage surface. Human lubricin contains two mucin-like domains. The first mucin domain contains multiple copies of the peptide motif KEPAPTTT, with threonine residues that are critical for O-linked GalNAc-Gal-NeuAc sidechains. The second mucin-like domain is also threonine rich but does not contain the KEPAPTTT motif. It also contains a hemopexin-like (PEX) domain at its C-terminal that is suggested to be essential for extracellular matrix binding. Lack of proteoglycan 4 expression leads to premature joint failure. Its low concentration in synovial fluid following an injury is associated with increased cartilage damage and may play a role in development of osteoarthritis. Proteoglycan 4 is reported to reduce neuroinflammation and protect the blood-brain barrier after traumatic brain injury. It restores blood-brain barrier function and prevents post-traumatic loss of tight junction protein claudin 5 and reduces neuronal death. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physikalische Form

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.

Rekonstituierung

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.

Lagerung und Haltbarkeit

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.
