ATP Muscle Kit includes:(* items are included in replacement kit). 4 Tubes Glycerinated Skeletal Muscle (item# 203520)* 4 Dropper Vials ATP Solution* 4 Dropper Vials KCl and MgCI2 Solution* 4 Dropper Vials ATP, KCl, and MgCI2 Solution* 4× Magnifying Glasses Microscope Slides and Coverslips Needed but not included: Scissors Teasing Needles Millimeter Rulers Dissecting and Compound Microscopes (optional)

We prepare the ATP solutions as close tos hipping time as practical to reduce loss in chemical activity. When they arrive, refrigerate the solutions at 4 to 10° C and use them within 7 days. Place the tubes with muscle strips in a freezer compartment at -20 to -10° C. Each strip of glycerinated muscle can be cut into 2- to 3-cm lengths.

Grades 9-College. This activity is designed for minimal prep time and can be completed in one class period. Students can observe and measure the contraction of real muscle tissue using the materials included. The kit features glycerinated (preserved) muscle tissue that amazingly retains the ability to contract when ATP and the appropriate ions are added. The glycerinated muscle is processed from striated muscle tissue. During processing, much of the water-soluble content is extracted in cold glycerol, while the striations are left intact and can be easliy observed under low-power magnification.

Materials sufficient for a class of 16 to 32 students. With Instructions. Note: Perishable; please provide use date on order.
