Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations.

Excellent for slide making, or just viewing the various stages of mitosis.

This organism can be isolated from soil, wounds, and intestinal tracts of humans. It digests protein and is known for its strong, distinctive odor.

Yeast strains are ideal for genetic study because they are easy to grow and maintain, their life cycle is complete in approximately one week, and you can arrest different stages of the life cycle by growing it on different types of media.

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

Characterized by flagella; lacks plastids.

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

Use these thin-section slides with a polarizing microscope to view rock specimens in detail. Includes: biotite granite, olivine basalt, red sandstone, encrinal limestone, mica schist, augen gneiss, storage box and identification guide.

Note: collections are subject to change depending upon availability of individual items. Set of six.

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

Planaria are a flatworm commonly used in science fair projects. They do not bite and move very slowly, making them easy for young students to observe.

One of the largest Drosophila species. Useful for preparing salivary gland chromosome squashes.

Mature Drosophila are cultured in our own labs, and are marked with the culture initiation date. Culture is shipped in our instant medium in a shatterproof vial. The Fruit Fly pupae will usually appear within ten days of the ship date. You will also receive WARD’S Drosophila Culture Guide. Note: We can supply any of our single strains in the larger quantity for 100 students. Call our Customer Service department for details.

Create a balanced ecosystem in your aquarium with the addition of these small, freshwater algae eaters. They reproduce rapidly, laying their eggs on the glass sides of the aquarium.

Bullfrog tadpoles are great for demonstrating metamorphosis in the classroom.

A. tumefaciens is a pathogenic soil bacterium known to cause grown gall disease, in nut trees and the plants of some stone fruits.

E. coli with JM101 can be transformed with pUC8 plasmid to become resistant to Ampicillin and to metabolize lactose

This organism is an aerobic organism that is commonly found as part of normal human intestinal flora. It is pathogenic.

All microbial cultures undergo an extensive quality control program prior to releasing for sale, so they are guaranteed for purity as well as for species.
