Description

Accession
P01127
Source
Optimized DNA sequence encoding Human PDGF-AB mature chain was expressed in Escherichia Coli.
Molecular weight
Recombinant Human PDGF-AB is a disulfide-linked heterodimer protein consisting of amino acid residue subunits(alpha+beta chains), and migrates as an approximately kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE.
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
The ED(50) was determined by the dose-dependentstimulation of thymidine uptake by BALB/cT3 was found to be in the range of1 ng/ml.

Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than.1 ng/µg(1EU/µg).
Presentation
PDGF-AB was lyophilized from a.2 μm filtered solution in PBS pH.4.
Reconstitution
A quick spin of the vial followed by reconstitution in distilled water to a concentration not less than.1 mg/mL. This solution can then be diluted into other buffers
Storage
The lyophilized protein is stable for at least years from date of receipt at -20° C. Upon reconstitution, this cytokine can be stored in working aliquots at° -° C for one month, or at -20° C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.

Methods

Neural progenitor cell isolation and maintenance

  • All procedures were performed in sterile fashion in a class II biosafety cabinet.
  • A representative portion (2.5 cm) of three regions (thoracic, cervical and lumbar) of the spinal cord was used for Neural Progenitor Cell (NPC) isolation as described previously.
  • Briefly, tissue was diced and a single cell suspension was obtained by enzymatic dissociation of the tissue at 37 °C for approximately 30–40 minutes with 2.5 U/ml papain , 250 U/ml of DNase I , and 1 U/ml neutral protease .
  • After dissociation, the cell suspension was mixed with DMEM/F12 with 10% fetal bovine serum (FBS, , ), passed through a 70 μM filter, and centrifuged.
  • The cell pellet was resuspended in DMEM/F12 with 10% FBS and combined 1:1 with percoll (GE Healthcare, Piscataway, NJ).
  • The cell/percoll mixture was centrifuged at 20,000 g for 30 min at room temperature and the low buoyancy fraction (10 ml) above the red blood cell layer…
