The Bioassay laboratory provides various kinds of screening services to evaluate the biological activities of crude or purified natural products, natural product derivatives and synthetic compounds. The tests can be done at a single or multiple concentrations for the analysis of effective concentration values, e.g. IC50 and MIC. Available services are as follows.

1. Cytotoxicity tests against mammalian cell lines
These assays investigate the ability of compounds to inhibit cell growth. Assays based on fluorometric (resazurin microplate assay) detection of viable cells, or measurement of green fluorescent protein (GFP) expressing cell mass, depending on cell types.

Available cell lines include:

  • MCF-7 (human breast adenocarcinoma)
  • NCI-H187 (human small cell lung, carcinoma)
  • HepG2 (human hepatocarcinoma)
  • Caco-2 (human colon adenocarcinoma)
  • B16-F10 (mouse melanoma)
  • Vero (African green monkey kidney)
  • NCTC929 (mouse subcutaneous connective tissue)
  • Human dermal skin fibroblast

2. Anti-human and animal infectious pathogens
The susceptibility of pathogens to compound can be investigated by observing its growth inhibitory effects. The assays provided include anti-malarial parasite (Plasmodium falciparum), anti-TB (Mycobacterium tuberculosis), anti-herpes simplex virus type 1(HSV-1), anti-Candida albicans, anti-Gram positive bacteria (Bacillus cereusEnterococcus faecium and Staphylococcus aureus) and anti-Gram negative bacteria (Pseudomonas aeruginosa (PAO1), Acinetobacter baumannii, Klebsiella pneumoniae and Escherichia coli). 

3. Anti-plant disease pathogens
These assays investigate the ability of compounds to inhibit fungal spore development based on staining of spore germ-links with a fluorescent dye, carboxy fluorescein diacetate (CFDA). The assays provided are anti-rice blast disease pathogen (Magnaportha grisea), anti-dirty panicle disease pathogen (Curvularia lunata) and anti- leaf spot disease pathogen (Alternaria brassicicola).

4. Mycoplasma testing of cultured cells
The assay tests for the presence of mycoplasma in cell cultures using MycoProbe Mycoplasma Detection kit (R&D systems), which requires a 1.5-ml sample of culture medium from cells grown without antibiotics for at least two weeks

Available services are as follows;

1. anti- Plasmodium falciparuman (K1 strain)
2. anti- Mycobacterium tuberculosis (H37Ra)
3. anti- Bacillus cereus
4. anti- Enterococcus faecium
5. anti- Staphylococcus aureus
6. anti- Pseudomonas aeruginosa (PAO1)
7. anti- Acinetobacter baumannii
8. anti- Klebsiella pneumoniae
9. anti- Escherichia coli
10. anti- rice blast disease fungi (Magnaportha grisea)
11. anti-dirty panicle disease fungi (Curvularia lunata)
12. anti- leaf spot disease fungi (Alternaria brassicicola)
13. anti- Candida albicans
14. anti- Herpes simplex type-1 (HSV-1)
15. Cytotoxicity against to Vero cell (African green monkey kidney fibroblast)
16. Cytotoxicity against to MCF-7 cell line (human breast adenocarcinoma)
17. Cytotoxicity against to NCI-H187 cell line (human small-cell lung carcinoma)
18. Cytotoxicity against to HepG2 cell line (human hepatocarcinoma)
19. Cytotoxicity against to Caco-2 cell line (human colon adenocarcinoma)
20. Cytotoxicity against to B16-F10 cell line (mouse melanoma)
21. Cytotoxicity against to human dermal skin fibroblast
22. Cytotoxicity against to NCTC929 cell line (mouse subcutaneous connective tissue)
23. Mycoplasma contamination test
