Abstract
To develop and validate a novel reporter gene assay (RGA) to detect pyrogen, HL60 cells were transfected with an NF-κB-RE plasmid containing the luciferase gene to generate stably transfected cells. Through stimulation with pyrogens, a signal was obtained that was dose-dependent with the concentration of pyrogen. Using the cells, we selected and optimized the parameters and found that the optimal conditions may be with 5 × 105/ml cells that were seeded and incubated with pyrogen for 3-6 h in IMDM medium with 2% FBS. Based on the optimized parameters, a novel RGA was developed. Then, the RGA was validated and the results showed that the linearity was greater than 0.95 between the signals and the concentrations of pyrogen, the recoveries of pyrogen were all between 50% and 200%, and the precision was less than 35%. There was no difference in the sensitivity, specificity or reproducibility between RGA and BET, and the results from RGA and MAT and RPT were consistent. Furthermore, the RGA can be applied to the pyrogen detection of monoclonal antibodies. Due to its advantages including a fast detection speed, high sensitivity, convenient mode of operation and wide-pyrogen spectrum detection, RGA is promising as a supplementary method to detect pyrogen.

Abstract
Background::
Pyrogens are fever-inducing substances and pyrogen detection is mandatory in
parenteral pharmaceuticals. Succinylated Gelatin Injection (SGI) is a biopharmaceutical product, containing
multi-component, and it is administered parenterally.
Objective:
The study aimed to assess pyrogen in SGI and to evaluate the feasibility of the Monocyte
Activation Test (MAT) for pyrogen detection in a multi-component pharmaceutical product.
Method:
In the present study, the Bacterial Endotoxin Test (BET) and the Monocyte Activation Test
(MAT) were employed to assess pyrogen in SGI. The MAT method was developed on the basis of the
HL-60/IL-6 assay. HL-60 cells were incubated with lipopolysaccharide (LPS) standards and sample
solutions. The endotoxin produced by the incubation, interleukin-6 (IL-6), was measured by ELISA.
The MAT method was validated and main parameters were investigated. Finally, the pyrogenicity of
SGIs from two different enterprises was determined by the developed MAT method.
Results:
The BET failed in the test for interfering factors and the MAT was proved suitable for the pyrogen
detection of SGI. All the products examined showed negative results in the pyrogen detection
test.
Conclusion:
The MAT method is feasible in pyrogen detection of SGI. It can be applied in pyrogen
detection for quality and safety control of multi-component biological products.
