Application Details

Restrictions: For Research Use only

Handling

Format: Lyophilized

Reconstitution: Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 μg or less, at 1 mg/mL for 500 μg or 1 mg lyophilized powder. Do not mix by vortex or vigorous shaking.

Buffer: Lyophilized from 0.22 μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.

Storage: -20 °C,-80 °C

Storage Comment: -20 to -80°C for 24 months as supplied from date of receipt.,-80°C for 3 months after reconstitution.,Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.

Expiry Date: 24 months

Target Details

Target: IL4 Receptor (IL4R) (Interleukin 4 Receptor (IL4R))

Alternative Name: IL-4 R alpha

Background: Interleukin 4 Receptor alpha (IL-4 Ra), also known as CD124 and BSF receptor, is a widely expressed 140 kDa transmembrane glycoprotein in the class I cytokine receptor family. The effects of IL-4 are mediated after binding to high affinity receptor complexes present on hematopoietic as well as non-hematopoietic cells.

Molecular Weight: 50.7 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Bis-Tris PAGE result.

UniProt: P24394

Pathways: JAK-STAT Signaling, Positive Regulation of Immune Effector Process
