C-Reactive Protein (CRP) (174-185)
Based on 1 Customer Validation
C-Reactive Protein (CRP) is an anti-pneumococcal plasma protein that can serve as an inflammatory marker. C-Reactive protein can protect mice from pneumococcal infection by activating complement. C-Reactive protein can inhibit the activation of caspase-3/9 through the CD64/AKT/mTOR pathway, thereby promoting chemotherapy resistance in mice with tongue squamous cell carcinoma.

Biological Activity
C-Reactive Protein (CRP) (0-25 μg/mL; 24 h) promotes monocyte migration by stimulating 3T3-L1 adipocytes to produce CXCL7[3]. C-Reactive Protein (CRP) can impair G1/S-dependent regeneration of renal tubular epithelial cells[4]. C-Reactive Protein (CRP) (10 μg/mL, 4 days) can enhance TSCC cell viability and increase cell resistance to DDP[5]. C-Reactive Protein (CRP) is a highly structurally conserved major acute phase plasma protein in humans[6].
