Biological Description

Biological Information	Measured by its binding ability in a functional ELISA. Immobilized Human CD27 His at 2 μg/ml (100 μl/well) can bind Human CD70 hFc , the EC50 of Human CD70 hFc is 15-60 ng/mL.
Description	CD70 Protein, Human, Recombinant (hFc) is expressed in HEK293 mammalian cells with hFc tag. The predicted molecular weight is 45.5 kDa and the accession number is A0A0U5JA32.
Species	Human
Expression System	HEK293 Cells
Tag	N-hFc
Accession Number	A0A0U5JA32
Synonyms	TNFSF7,CD27L,CD27LG,CD70 molecule
Construction	The extracellular domain of Human CD70 (NP_001243.1) (Gln 39-Pro 193) was fused with the Fc region of Human IgG1 at the N-terminus via a polypeptide linker.
Protein Purity	> 90 % as determined by SDS-PAGE
Molecular Weight	45.5 kDa (predicted)
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	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
Stability & 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.
Shipping	In general, Lyophilized powders are shipping with blue ice.
Research Background	CD70, a member of the tumor necrosis factor superfamily, is restricted to activated T-and B-lymphocytes and mature dendritic cells. Binding of CD70 to its receptor, CD27, is important in priming, effector functions, differentiation and memory formation of T-cells as well as plasma and memory B-cell generation. Tight control of CD70 expression is required to prevent lethal immunodeficiency. By selective transcription, CD70 is largely confined to activated lymphocytes and dendritic cells (DC). As a type II transmembrane receptor, CD70 is normally expressed on a subset of B, T and NK cells, where it plays a costimulatory role in immune cell activation. Immunohistochemical analysis of CD70 expression in multiple carcinoma types. The restricted expression pattern of CD70 in normal tissues and its widespread expression in various malignancies makes it an attractive target for antibody-based therapeutics. Investigations to exploit CD70 as a cancer target have lead to the identification of potential antibody-based clinical candidates.Cancer ImmunotherapyCo-stimulatory Immune Checkpoint TargetsImmune CheckpointImmune Checkpoint ProteinsImmune Checkpoint TargetsImmunotherapyTargeted Therapy
