OMGP Protein, Human, Recombinant (aa 1-416, His Tag)

• Background:

  Oligodendrocyte-myelin glycoprotein, also known as OMG and OMGP, is a cell membrane protein that contains eight LRR (leucine-rich) repeats. OMG / OMGP is a glycosylphosphatidylinositol-anchored protein expressed by neurons and oligodendrocytes in the central nervous system (CNS) . OMG / OMGP is a cell adhesion molecule contributing to the interactive process required for myelination in the central nervous system. OMG / OMGP play roles in both the developing and adult central nervous system. OMG / OMGP participates in growth cone collapse and inhibition of neurite outgrowth through its interaction with NgR, the receptor for Nogo. This function requires its leucine-rich repeat domain, a highly conserved region in OMgp during mammal evolution. OMG / OMGP leucine-rich repeat domain is also implicated in the inhibition of cell proliferation. OMG / OMGP may also be involved in the formation and maintenance of myelin sheaths. Cell proliferation, neuronal sprouting, and myelination are crucial processes involved in brain development and regeneration after injury.

  P23515-1

• Expression System:

  HEK293 Cells

• Tag:

  C-His

• Endotoxin:

  < 1.0 EU per μg of the protein as determined by the LAL method.

• Purity:

  > 97 % as determined by SDS-PAGE.

• Activity:

  At Leading Biology, the biological activity of a recombinant protein is routinely measured using a bioassay, e.g. chemotaxis or cell proliferation assay, enzyme assay, or a functional ELISA. When a recombinant protein is an enzyme, specific activity is derived from an enzymatic assay. Each enzyme is tested for potency by cleavage of a substrate. We are in the process of updating the biological activity data. If you have any questions regarding this update, please feel free to contact our technical support team.

• Form:

  Lyophilized

• Buffer:

  Lyophilized from sterile PBS, pH 7.4. Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.

• Molecular Weight:

  The secreted recombinant human OMGP comprises 403 amino acids and has a predicted molecular mass of 46 kDa. The apparent molecular mass of rh OMGP is approximately 120-130 kDa in SDS-PAGE under reducing conditions due to high glycosylation.

• Storage Conditions:

  In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise. Stable for 1 year at -20°C or below from date of shipment. For maximum recovery of product, centrifuge the original vial after thawing and opening the cap. For long-term storage, aliquot and store at -20°C or below. Avoid repeated freeze-thaw cycles.
