Recombinant Rat CRP/C-Reactive Protein (His Tag)

• Background:

  Displays several functions associated with host defense: it promotes agglutination, bacterial capsular swelling, phagocytosis and complement fixation through its calcium-dependent binding to phosphorylcholine. Can interact with DNA and histones and may scavenge nuclear material released from damaged circulating cells.

• Abbreviation:

  CRP, C-Reactive

• Synonyms:

  C Reactive Protein Pentraxin Related Protein; MGC88244; PTX 1; Pentraxin 1

• UniProt:

  P48199

• Accession Number:

  P48199-1

• Expression System:

  E. coli

• Tag:

  N-His

• Sequence:

  His20-Ser230

• Endotoxin:

  < 10 EU/mg of the protein as determined by the LAL method.

• Purity:

  > 85% as determined by reducing SDS-PAGE.

• Bioactivity:

  Not validated for activity

• Reconstitution:

  It is recommended that sterile water be added to the vial to prepare a stock solution of 0.5 mg/mL. Concentration is measured by UV-Vis.

• Shipping Conditions:

  This product is provided as lyophilized powder which is shipped with ice packs.

• Storage Conditions:

  Generally, lyophilized proteins are stable for up to 12 months when stored at -20 to -80°C. Reconstituted protein solution can be stored at 4-8°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.

• Calculated Molecular Weight:

  23.3 kDa

• Observed Molecular Weight:

  24.7 kDa

• Formulation:

  Lyophilized from sterile PBS, pH 7.4.
  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 printed manual.
