Target Name: Interleukin-4; IL-4; B-Cell Stimulatory Factor 1; BSF-1; Binetrakin; Lymphocyte Stimulatory Factor 1; Pitrakinra; IL4

Source: Recombinant Human IL-4 (accession number P05112) (His25-Ser153) is expressed in HEK293 cells.

Molecular Weight: The 129 amino acid protein has a predicted molecular weight of 14.97 kDa. The protein migrates at approximately 18 kDa on SDS-PAGE with DTT-reduced condition.

Purity: >95% based on SDS-PAGE

Formulation: Lyophilized from a 0.2 μm filtered PBS, pH 7.4.

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.
