Labcon Reusable Tube Racks

  • 25-Place
  • Autoclavable (122°C) and freezable (-80°C)
  • Numbered Wells
  • Made of polypropylene 

These racks are designed to hold Labcon centrifuge tubes. Unlike foam racks, they are autoclavable and will not fall apart with repeated use. They can be frozen, and they stack together to minimize storage space. An interlocking design lets you connect more than one rack to create a handy workstation. Autoclavable (122°C) and freezable (-80°C).

 

Expandable tube racks can be assembled to hold 5 mL, 15 mL, and 50 mL tubes. You can link sections of 25 to suit your needs. Made of polypropylene.

 

These racks are designed for Labcon centrifuge tubes, other tube brands may not fit correctly.

PR1MA Phleomycin, Powder

CAS Number: 11006-33-0
Molecular Weight: 1525
Chemical Formula: C55H85O21N202Cu 
 HCl
Solubility: Water
Storage Temp: 2-8°C

Produced by Streptomyces verticillus and part of the structurally related group of Bleomycin/Phleomycin type antibiotics. Used as a selective agent in transformation experiments with mammalian cells, plant cells, and yeast. Cytotoxic action of this type of antibiotic results from the ability to cause fragmentation of DNA. In Vitro studies indicate that Phleomycin causes the accumulation of cells in the G2 phase of the cell cycle.

Research or further manufacturing use only, not for food or drug use.

  • Appearance: Light Blue Powder
  • U.V. Absorbance (244nm, 600 µg/ml, 0.1cm Path): 0.20 - 0.30
  • Storage Condition: Store at 2 - 8 oC (Very Hygroscopic: Keep container tightly sealed until ready for use).
