Product Introduction

Bioactivity

Bioactivity	Immobilized Human CD93 (His Tag) at 2 μg/ml (100 μl/well) can bind Human IGFBP7 (hFc Tag). The EC50 is 8-60 ng/ml.
Description	CD93/C1qR1 Protein, Human, Recombinant (His) is expressed in HEK293 mammalian cells with His tag. The predicted molecular weight is 59.6 kDa and the accession number is Q9NPY3.
Species	Human
Expression System	HEK293 Cells
Tag	C-His
Accession Number	Q9NPY3
Construction	A DNA sequence encoding the human CD93 (Q9NPY3) extracellular domain (Met 1-Lys 580) was fused with a polyhistidine tag at the C-terminus. Predicted N terminal: Thr 22
Protein Purity	≥ 90 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC. ,
Endotoxin	< 1.0 EU/μg of the protein as determined by the LAL method.
Formulation	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
Reconstitution	Reconstituted with sterile deionized water to 0.25 mg/mL. Reconstitution conditions may vary depending on the lot.
Synonyms	MXRA4, ECSM3, dJ737E23.1, CDw93, CD93 molecule, C1qRP, C1QR1, C1qR(P), C1qR
Research Background	CD93 or C1q receptor 1 (C1qR) is an about 120 kDa O-sialoglycoprotein that within the hematopoietic system is selectively expressed on cells of the myeloid lineage. CD93/C1qR is a highly glycosylated transmembrane protein expressed on monocytes, neutrophils, endothelial cells, and stem cells. CD93 was originally identified as a myeloid cell-surface marker and subsequently associated with an ability to modulate phagocytosis of suboptimally opsonized immunoglobulin G and complement particles in vitro. CD93/C1qR, a receptor expressed during early B-cell development, is reinduced during plasma-cell differentiation. High CD93/CD138 expression was restricted to antibody-secreting cells both in T-dependent and T-independent responses as naive, memory, and germinal-center B cells remained CD93-negative. CD93 was expressed on (pre)plasmablasts/plasma cells, including long-lived plasma cells that showed decreased cell cycle activity, high levels of isotype-switched Ig secretion, and modification of the transcriptional network. CD93 is important for the maintenance of plasma cells in bone marrow niches.

Storage & Solubility Information

Shipping	In general, lyophilized powders are shipped with blue ice, while solutions are shipped with dry ice.
Storage	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
