For Research Use Only. Not for use in diagnostic procedures.

Chromosome: 1; NC_000001.10 (186265405..186283688). Location: 1q25-q31

E Coli

> 95%

Supplied as lyophilized form in PBS,pH7.4, containing 5% sucrose, 0.01% sarcosyl.

Avoid repeated freeze/thaw cycles. Store at 2-8 degree C for one month. Aliquot and store at -80 degree C for 12 months.
Stability Test: The thermal stability is described by the loss rate of the targetprotein. The loss rate was determined by accelerated thermal degradation test,that is, incubate the protein at 37 degree C for 48h, and no obvious degradation andprecipitation were observed. (Referring from China Biological Products Standard,which was calculated by the Arrhenius equation.) The loss of this protein is lessthan 5% within the expiration date under appropriate storage condition.

Manufactured in an ISO 9001:2008 and ISO 13485:2003 Certified Laboratory.

Manufactured in a lab with traceable raw materials. Bulk orders can typically be prepared to the customer’s specifications, please inquire.

Small volumes of PRG4 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

The protein encoded by this gene is a large proteoglycan that is synthesized by chondrocytes located at the surface of articular cartilage and by some synovial lining cells. This protein contains both chondroitin sulfate and keratan sulfate glycosaminoglycans. It functions as a boundary lubricant at the cartilage surface and contributes to the elastic absorption and energy dissipation of synovial fluid. Mutations in this gene result in camptodactyly-arthropathy-coxa vara-pericarditis syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2014]

PRG4: Plays a role in boundary lubrication within articulating joints. 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. Defects in PRG4 are the cause of camptodactyly- arthropathy-coxa vara-pericarditis syndrome (CACP); also known as Jacobs syndrome. CACP is an autosomal recessive disorder. Individuals with CACP have normal appearing joints at birth but with advancing age develop joint failure associated with noninflammatory synoviocyte hyperplasia and subintimal fibrosis of the synovial capsule. 6 isoforms of the human protein are produced by alternative splicing.
