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.
There are basically two types of syringes that can be used to inject methotrexate: U-100 Insulin Syringes or 1cc/1mL syringes. NOTE: 1cc=1mL=U-100 (100 Units)! 3. All of these small syringes are capable of holding a maximum of 25 mg of methotrexate. 4. Needle Length: The syringes all come with needles which are either 5/16â (8 mm=short) or Â½â (12.7 mm) long. 5.
