  • What types of acrylamide are available in Bio-Rad?
  • Bio-Rad offers high purity acrylamide in three forms: acrylamide powders, premixed acrylamide/bis powders, and acrylamide solutions. Bio-Rad offers both highly purified SDS powder and 10% and 20% SDS solutions. Tween 20 for blotting and Triton X-100 and CHAPS for membrane protein solubilization are also available.
  • Does polyacrylamide separate ha well?
  • Gels containing 5%, 10%, and 15% polyacrylamide were found to separate HA well, but did not resolve a sufficiently broad molecular mass range in the short gels. An improved separation covering a broader range of molecular mass was obtained using a commercial 4–20% gradient polyacrylamide gel.
  • Which polyacrylamide gel is used to separate a 37 kDa ha sample?
  • For the 37 kDa HA sample, 3–4% agarose and the 4–20% gradient polyacrylamide gel gave equivalent results (weight-average molecular mass of 28–30 kDa). For the smallest HA sample of 22 kDa, only the polyacrylamide gel matrix was able to separate the sample, and allow determination of its weight-average molecular mass (20 kDa).
  • What does %t mean in polyacrylamide gel?
  • %T indicates the relative pore size of the resulting polyacrylamide gel: higher %T refers to a larger polymer-to-water ratio and on average smaller pores. The practical ranges for monomer concentration are stock solutions of 30-40%, with different ratios of acrylamide monomer to crosslinker.
