Target Name: Interleukin-13;IL-13

Source: Recombinant Human IL-13 (accession number AAH96139) (Gly21-Asn132) with a 6His tag at the C-terminus is expressed in HEK293 cells.

Molecular Weight: The 112 amino acid protein has a predicted molecular weight of 13.4 kDa. The protein migrates at approximately 13-30kDa on SDS-PAGE with DTT-reduced conditions (due to different glycosylation)

Formulation: Lyophilized from a 0.2 μm filtered solution of PBS, PH7.4.

Vial Size: 10µg, 50µg

Endotoxin Level: Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

Reconstitution: Always centrifuge tubes before opening. Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100 μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.

Storage and Handling: Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
