Other Notes

Cultures from HPA Culture Collections and supplied by Sigma are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line. Please view the Terms & Conditions of Supply for more information.


THP 1 cell line human has been used to study:
• bactericidal activity of moxifloxacin against Staphylococcus aureus
• the effect of lipopolysaccharide-mediated inflammatory response in murine versus human cell lines
• the effects of purine nucleosides on the in vitro growth of Cryptosporidium parvum
• the change in gene expression after infection with Mycobacterium tuberculosis
• the induction of cytokines in the cell line in presence of antigens obtained from Clostridium difficile

Culture Medium

RPMI 1640 + 2mM Glutamine + 10% Foetal Bovine Serum (FBS / FCS).

Subculture Routine

If starting from a frozen ampoule, add thawed cells to a conical based centrifuge tube e.g. 15ml tube. Slowly add 4 ml of culture medium to the tube. Take a sample of the cell suspension, e.g. 100ul, to count cells. Centrifuge the cell suspension at low speed i.e. 100 - 150 x g for a maximum of 5 minutes. Remove medium and resuspend the cell pellet at a density of 3 - 5 x 100,000 cells/ml in fresh medium containing 20% serum. Incubate flask at 37 C; 5 - 7% CO2. Check daily. Keep flask in a vertical position until the cells reach the exponential phase of growth. This can take up to 7 days. Once the culture is established the serum concentration can be reduced to 10%. To keep the cells in exponential growth, maintain cultures between 3-8x100,000 cells/ml. Requires glycerol as cryoprotectant. Growing orders are recommended due to difficulties that can be experienced during the initial start-up of this cell line. Replacements will be charged at full cost where claims cannot be substantiated.

Cell Line Description

Derived from the peripheral blood of a 1 year old male with acute monocytic leukaemia. THP-1 cells have Fc and C3b receptors and lack surface and cytoplasmic immunoglobulins. These cells also stain positive for α-napthhyl butyrate esterase, produce lysozymes and are phagocytic (both latex beads and sensitised erythrocytes). THP-1 cells can also restore the response of purified T lymphocytes to Concanavlin A, show increased CO2 production on phagocytosis and can be differentiated into macrophage-like cells using for example DMSO.Growing orders are recommended due to difficulties that can be experienced during the initial start-up of this cell line. Please note: We routinely resuscitate and culture this cell line with success, however, some laboratories have found this cell line difficult to establish following resuscitation from a frozen ampoule. Our Quality Control (QC) Department strongly recommend that this line is supplied as a Growing culture whenever possible e.g. to locations within or near the European Union. We routinely resuscitate and maintain this cell line growing in our laboratory to enable us to supply growing cultures quickly. If however, you still wish to receive the cell line Frozen we can supply but our normal replacement Policy will not apply should you encounter resuscitation difficulties.We recommend, if you are in the European Union (where we can deliver growing cultures), you select a Growing culture.

Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
How do I find price and availability?
There are several ways to find pricing and availability for our products.Once you log onto our website, you will find the price and availability displayed on the product detail page.You can contact any of our Customer Sales and Service offices to receive a quote. USA customers: 1-800-325-3010 orview local office numbers.
Howdo Ihandle Cell Linefrozen cells upon arrival?
Upon receipt, frozen ampules should be transferred directly to vapor phase liquid nitrogen without delay (-135°C) or liquid phase liquid nitrogen if vapor phase is not available. DO NOT use a -80°C freezer as an alternative; this will result in loss of viability.
Why is Vapor Phase Liquid Nitrogen preferred for storage of Cell Linecells?
If ampules are immersed into liquid phase of liquid nitrogen, it increases the risk of the liquid seeping into the vial. This could lead to problems of cross-contamination and increased risk of the ampule exploding when thawed.
How do I resuscitate/thaw frozen Cell Line cells?
A protocol for thawing cells can be found in the ECACC handbook.
What medium should I use when I thaw the Cell Linecells?
The medium for each cell line is listed on the product page. It is specific to each cell line. If not visible on the Sigma-Aldrich website product page, the HPA website also contains the same information ( The product number for the cell line is the same on either site.
What passage are my Cell Line cells?
If the passage of the cells is known, it is listed on the product page at the HPA website (
How many Cell Linecells are in the vial?
Each vial of cells contains 2-3 x 106 cells in 1 ml of freezing media. This is in a 1.8 mL ampule. For exceptionally large cells, counts may decrease. Suspension cells, generally smaller cells, may contain as many as 4-5 x 106 cells/vial to assure optimal viability upon thaw.
Are my Cell Linecells mycoplasma tested?
ECACC routinely tests all manufactured cell banks for mycoplasma.
How to freeze down Cell Linecells to make a cell stock?
A protocol for freezing down cells for cell stocks can be found in the ECACC manual.
Are the Cell Linecells tested for viral pathogens?
HPA Cultures does not perform any viral testing on the cell lines.
