IL-3R alpha/CD123 Protein, Human (HEK293, Llama Fc)

FITC-tagged IL-3R α/CD123 is a cell surface receptor for IL3 expressed on hematopoietic progenitor cells, monocytes, and B lymphocytes, regulating their production and differentiation. IL-3R alpha/CD123 Protein, Human (HEK293, Llama Fc) is the recombinant human-derived IL-3R alpha/CD123 protein, expressed by HEK293, with C-Llama Fc labeled tag.

IL-3R alpha/CD123 Protein serves as a cell surface receptor for IL3 and is expressed on hematopoietic progenitor cells, monocytes, and B-lymphocytes, exerting control over the production and differentiation of hematopoietic progenitor cells into lineage-restricted cells. Upon ligand stimulation, it rapidly undergoes heterodimerization with IL3RB, leading to the phosphorylation and activation of effector proteins, including JAK2 and PI3K. These activated pathways play a crucial role in signaling cell proliferation and differentiation. JAK2 activation further initiates a STAT5-mediated transcriptional program, contributing to the regulation of cellular functions. The receptor interacts with its ligand, IL3, and forms a heterodimer consisting of an alpha and a beta subunit. Notably, the beta subunit is shared among the receptors for IL3, IL5, and GM-CSF.

Extracellular Domain

Approximately 45 kDa & 55 kDa & 80 kDa,based on SDS-PAGE under reducing conditions,due to the glycosylation.

Greater than 90% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from 0.22 μm filtered solution of Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
