C-Reactive Protein, Human (His)

C-Reactive Protein, an acute-phase protein, is a marker of inflammation and is produced by the liver. It is used as a diagnostic tool to assess the presence and severity of inflammation in various diseases. C-Reactive Protein's role in inflammation detection and its clinical significance in disease management make it a subject of interest in medical research. C-Reactive Protein, Human (His) is the recombinant human-derived C-Reactive protein, expressed by E. coli , with C-6*His labeled tag. The total length of C-Reactive Protein, Human (His) is 206 a.a., with molecular weight of ~27.0 kDa.

C-Reactive Protein (CRP) exhibits various functions related to host defense. It facilitates agglutination, bacterial capsular swelling, phagocytosis, and complement fixation by binding to phosphorylcholine in a calcium-dependent manner. CRP is also capable of interacting with DNA and histones, and it may scavenge nuclear material that is released from damaged circulating cells.

Approximately 27.0 kDa

Greater than 95% as determined by reducing SDS-PAGE

Lyophilized powder.

Lyophilized from a 0.2 μm filtered solution of 20 mM Tris-HCl, 2 M Urea, pH 8.0.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
