Protists - Living Material

Freshwater. Filamentous. Produces zoospores. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Marine. Unicellular; brackish, centric cells. Marine medium.

Characterized by shells (tests) made of silica, in two parts.

Marine. Unicellular. Erdschreiber’s medium.

Characterized by reddish plastids (rhodoplasts).

With stiff 'arms' radiating in all directions, these microscopic organisms look like sea urchins

Freshwater. Colonial; net-like structure with multinucleated cells. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; triangular desmid. Basic culture solution. Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Unicellular; heart-shaped cell. Soil-water medium.

Characterized by a lack of rigid cellulosic walls, instead these organisms have pellicles made of protein. They store paramylon instead of starch.

Marine. Unicellular; contains same pigments as other Golden Algae but contains haptonema, unique to Haptophyceae. Coccoid, from coccoliths. Marine medium. Characterized by golden yellow plastids.

Axenic culture. Food organism. Tetrahymena medium.

Characterized by cilia; nearly all possess two types of nuclei.

The body of this ciliate is transparent, making the large cilia clearly visible.

Live Cultures are supplied with media in 16 x 125 mm tubes, 2 oz. jars, or 8 oz. jars. Fast delivery is available directly from our laboratory. Please specify a delivery date.

Each culture shipment is prepared in our laboratories and includes the "Working with Protozoans" manual which contains detailed instructions for subculturing and use.

Canadian Customers:
CFIA and PHAC regulations require customers to submit a completed inspection checklist and signed statement of facilities compliance before receiving certain cultures. A customer service representative will contact you if documentation is required.

Our cultures undergo strict biochemical screening and are unconditionally guaranteed for species and purity. Each culture is labeled with scientific name, media on which it was cultivated and optimum growth temperature. Although our cultures are considered non-pathogenic, standard bacteriological laboratory procedures should be used at all times. Cultures are available either live for immediate use or freeze-dried for convenient storage until needed. (Please note: We are not responsible for any infection resulting from the use of our cultures.)

Freshwater. Filamentous. Basic culture solution.

Characterized by reddish plastids (rhodoplasts).

Marine, Macroalga, Multicellular; membranous thallus. Collected. Characterized by green plastids and cell walls composed of cellulose.

Marine. Filamentous; polysiphonious construction. Collected.

Characterized by reddish plastids (rhodoplasts).

Spirogyra is a genus of filamentous green algae with chloroplasts arranged in a helical (spiral) pattern.

This species of freshwater algae is commonly used for research on photosynthesis.

Volvox globator is a species of colonial green algae that forms spherical colonies of cells.
