PRODUCT DATA   HUMAN SERUM PROTEINS


Product: IMMUNOGLOBULIN A (IgA)  


Code No: RDI-SCP143-3      $250.00/1mg     $425.00/10mg   $3125.00/10mg

Source material: Pooled Human serum/plasma.

Product presentation: Supplied as a frozen solution in 0.05M phosphate buffer pH 7.5, containing 0.15M NaCl and 0.1% NaN3.

Specification: > 96% Purity.

Analysis: Cellulose acetate electrophoresis shows one band only, with *2 to *2 electrophoretic   mobility.

SDS-PAGE shows one band only, corresponding to a molecular weight of approx. 160,000.

Quantitative (and qualitative) analysis by radial   immunodiffusion (RID). Levels of IgG and   IgM <1%. of level of IgA.

Protein determination by the method of Lowry 280nm and OD = 1.34.   1cm,0.1%

Material is composed predominantly of IgA, subclass 1.

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: Below -15oC


Product: IMMUNOGLOBULIN A (IgA) Code No: RDI-SCP143-0   ULTRA-PURE

Cat#RDI-SCP143-0 Ultra pure human IgA

$375.00/1mg     $1250.00/10mg     $6250.00/100mg   Larger or intermediate sizes  on request

Source material: Human serum/plasma. Derived from product RDI-SCP143-3.

Product presentation: Supplied as a frozen solution in 0.05M phosphate buffer pH 7.5, containing 0.15M NaCl and 0.1% NaN3.

Specification: >99% purity

Purified to a level where no contaminating proteins can be detected using a range of analytical techniques. Suitable for use as an immunogen

Analysis: Cellulose acetate electrophoresis shows one band only, indicating B2 to Gamma2 electrophoretic mobility.

SDS-PAGE shows one band only, corresponding to a molecular weight of approx. 150,000.

Protein determination by the method of Lowry and OD280nm =1.34 1cm, 0.1%

Immunoelectrophoresis versus anti-whole human serum shows one species only, identified as IgA.

RID shows IgG and IgM to be undetectable. Lower limit for detection equivalent to 0.1% of total protein.

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

Storage: Below -15oC. Shelf life minimum 1 years.
