CAT#: RDI-SCP1791     $750.00/1mg

Source material: Pooled Human serum/plasma

Product presentation: Supplies lyophilised from 0.02M NH4HCO3. May contain traces of buffer salts. The use of a buffered solution containing physiological levels of saline may aid complete dispersion of the product upon reconstitution.

Specification: CDT is here defined as including the presence of:

                      Asialo pI = 6.0           Monosialo pI = 5.85

                     Disialo pI = 5.7           Trisialo      pI = 5.6

                  CDT content nominally >96% of total transferrin.

Analysis: Isoform pI determined by IEF (transferrin isoforms are iron saturated before electrophoresis).

SDS-PAGE shows a tight cluster of bands, corresponding to a molecular weight of approx. 77,000. Dimer, may appear under certain conditions.

Total transferrin by radial immunodiffusion (RID).

Protein determination by the method of Lowry and OD(280nm).

CDT characterised by AXIS% CDTri TIA.

Disease state testing: Serum/plasma is donor tested and certified negative for HIV 1 and 2 antibodies, Hepatitis B surface antigen and HCV antibodies.

Storage: 2-8'C.
