Protists - Living Material

A very large Protozoa that graphically demonstrates the basic animal cell.

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.)

Demonstrates isogamous reproduction where gametes are similar in appearance and behavior. Make lectures and labs on protist reproduction clearer with our specially selected cultures that illustrate various reproductive phenomona.

Marine. Filamentous. Branched thallus, zoospores. Erdschreiber’s medium.

Kelp and seaweed; with a distinct set of photosynthetic pigments.

One jar containing a mixture of 6 different genera of algae. Each algae is cultured individually in Ward's laboratories, and mixed together immediately prior to shipment to ensure an adequate supply of each organism.

Extremely small euglenoid. Usually doesn’t rotate when swimming. Scavenger. Hay medium.

Characterized by flagella; lacks plastids.

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

For Culture of Freshwater Algae. Comes in ready-to-use and concentrated formulations

Organisms with Characteristics of Two Kingdoms

Water mold and fish parasite. Demonstrates sporangia and oospores. Grows on wheat seed, cucumber seed, or hemp seed in water environment. Reproduces sexually and asexually. Incubation temperature 25°C.

Cell walls made of cellulose; feeds by extending hyphae into host's tissue.

Cellular slime mold. Demonstrates amoeboid state, pseudoplasmodial state, and fruiting body, or sorocarp. Found in woodland soil in decomposing vegetation where bacteria are abundant. Incubation temperature 25°C. Plate cultures grown with Enterobacteria as food source; freeze-dried cultures include food source.

Characterized by an amoeboid stage (lacking cell walls) and a fungus-like reproductive structure.

Freshwater. Unicellular; large cells, with four flagella. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Demonstrates isogamous reproduction where gametes are similar in appearance and behavior. Make lectures and labs on protist reproduction clearer with our specially selected cultures that illustrate various reproductive phenomona.

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

Marine. Unicellular; small, centric cells. Marine medium.Characterized by shells (tests) made of silica, in two parts.

Freshwater. Filamentous; displays high degree of differentiation. Basic culture solution.

Characterized by green plastids and cell walls composed of cellulose.

Freshwater. Filamentous; H-shaped cell walls. Soil-water medium.

Characterized by green plastids and cell walls composed of cellulose.
