C-reactive protein (CRP)

Number: LD-CRP-02 (main push version)
Keyword:
C-reactive protein (CRP)
Product description

Project Introduction

C-reactive protein (CRP) is an acute phase protein. In the event of inflammation or tissue destruction, CRP has a faster induction time, shorter half-life, and greater variation, and its catabolism is not affected by the type of infection. CRP as a prompt indicator of systemic inflammatory diseases. CRP can be used to diagnose a variety of inflammatory diseases, such as: severe acute pancreatitis, acute appendicitis, meningitis, aspiration pneumonia, osteomyelitis, osteoarthritis, giant cell arthritis, neonatal sepsis, acute rhinitis, acute otitis media It is also used for extensive trauma, burns, post-operative bacterial syndrome and acute myocardial infarction.

Project Benefits

High linearity: the linear range of conventional parameters is 0.5-320mg/L, and it can even reach 0.5-400mg/L under specific parameters.

Rigorous traceability: It can be traced to the reference material ERM-DA474/IFCC, and it has passed the inter-laboratory quality assessment (EQA) with full marks.

Mass production upgrade: The unique "one-pot cooking" process makes it easy to supply thousands of liters of other reagents in a single batch.

Excellent correlation: The correlation coefficient r ≥ 0.99 between 50 specimens and the top nine was tested.

5) Good compatibility: compatible with a variety of serum, plasma and whole blood, compatible with biochemical analyzers, specific protein analyzers, blood cell analyzers and other instruments

CRP antigen

The company has many years of experience in the expression and purification of natural proteins and recombinant proteins, and has developed a recombinant CRP protein with excellent stability. With the company's supporting antigen preservation solution, it can ensure that the protein is in a liquid state and is heated at 37 ℃ for 14 days. The loss does not exceed 10%.

The following uses our company's C-reactive protein detection kit (latex-enhanced immune turbidimetry) to test the stability of the antigen. The results show that the CRP antigen was frozen and thawed at -40 °C for 4 times, and the deviation was within ±5%. within ±10%; under 37°C for 7 days, the deviation is within ±10%; for 2 months at 2-8°C, the deviation is within ±10%.
