Kda
Apparent Mol
Mass:
16
KDa, reducing conditions
Endotoxin:
<
1 EU/µg as determined by LAL test.
Formulation:
Lyophilized
from a 0.2 μm filtered solution of 20mM Histidine-HCl, 6% Sucrose, 4%
Mannitol, 0.02% Tween80 (w/v), pH 6.0.
Reconstitution:
Always
centrifuge tubes before opening.Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than
100μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw
cycles.
Shipping:
The
product is shipped at ambient temperature.
Upon receipt, store it immediately at the temperature listed below.
Storage:
Lyophilized
protein should be stored at ≤ -20°C, stable for one year after receipt.
Reconstituted protein solution can be stored at 2-8°C for 2-7 days.
Aliquots of reconstituted samples are stable at ≤ -20°C for 3 months.
Background:
At
least 23 different variants of Interferon-α are known. The individual
proteins have molecular masses between 19-26 kD and consist of proteins with
lengths of 156-166 and 172 amino acids. All IFN-α subtypes possess a common
conserved sequence region between amino acid positions 115-151 while the
amino-terminal ends are variable. Many IFN-α subtypes differ in their
sequences at only one or two positions. Naturally occurring variants also
include proteins truncated by 10 amino acids at the carboxyl-terminal end.
