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.
The best way to avoid infections is to use a new (sterile) needle and syringe each and every time you inject. Syringes are not designed to be used more than once. Never share a needle, syringe, cooker or cotton with anyone. Availability of new sterile needles and syringes is often hampered by legal and political issues.
