Natural Shrimp Tropomyosin (NA-STM-1)

Preservative-free and carrier-free in phosphate buffered saline, pH 7.4. Sterile filtered.

1. Additional bands below 36kD represent tropomyosin fragments.
2. Avoid repeated Freeze/Thaw cycles.
3. There are generally two species, the white (L.setiferus) and brown (F. aztecus) shrimp that overlap in seasons in the Carolina waters. Pink shrimp (F. duorarum) also occur, especially in North Carolina catches. Because of the overlap of three different species, we cannot specify the species, most likely it is a mixture.
