Biochemical analyses of sugary-1 mutants indicate that both types of starch debranching enzymes, isoamylase and pullulanase, are either missing or greatly reduced in the endosperms of maize (Pan and Nelson, 1984; Rahman et al., 1998) and rice (Nakamura et al., 1992, 1996b, 1997, and the present study).he present investigation has been carried out to examine the relationship between the activities of starch debranching enzymes and the alteration of amylopectin structure in various sugary-1 endosperms of rice by partitioning the endosperm into the starch region and the phytoglycogen region.
Glass syringes are the most common type of syringe used with a syringe pump. Glass syringes are typically compatible with most applications, reusable for multiple applications, and more accurate than most syringe types. The plunger of a glass syringe can be made of only ground glass, glass with a Teflon syringe tip type, metal-only, or metal with a Teflon tip.
1 The type of insulin should match the type of syringe: U-100 or U-500. Because U-500 syringes may be difficult to find, your health care provider may give you instructions for using U-500 insulin with U-100 syringes.  Some types of insulin can be mixed with each other in one syringe, but not all.
