This ELISA kit provides quantitative measurement of CCL2 (MCP-1) in rat samples, supporting immunology research focused on monocyte and macrophage recruitment during inflammatory responses. Because CCL2 levels can vary dramatically between baseline conditions and acute inflammatory states — and across compartments such as circulation versus local tissue microenvironments — selecting an assay with appropriate coverage and sensitivity is critical.
Detection Range: The 3.9–250 pg/mL range aligns with reported rat serum CCL2 concentrations, which typically remain low (tens of pg/mL) at baseline but rise sharply during injury or infection. Samples from LPS-challenged animals or inflamed tissue homogenates may require dilution to fall within range.
Sensitivity: At 1.95 pg/mL, the kit detects CCL2 in unstimulated cell culture supernatants and baseline serum, where concentrations often fall below 10 pg/mL — essential for capturing early chemokine induction kinetics.
Sample Compatibility: Validation across serum, plasma, cell culture supernatants, and tissue homogenates enables researchers to correlate systemic CCL2 levels with local tissue production and in vitro monocyte chemotaxis assays within a single experimental framework.
Assay Efficiency: The 1–5 hour protocol and 50–100 µL sample volume accommodate studies using primary rat macrophage cultures or serial blood draws, where sample availability is inherently limited.
This kit is well suited for studies of neuroinflammation, renal ischemia-reperfusion injury, and atherosclerosis progression in rat models.
