Biotinylated Human CD38 Protein, Avi Tag (Avitag™)

分子别名(Synonym)

CD38,T10,cADPr hydrolase 1

表达区间及表达系统(Source)

Biotinylated Human CD38, His Tag (CD8-H82E7) is expressed from human 293 cells (HEK293). It contains AA Val 43 - Ile 300 (Accession # NP_001766.2).

Predicted N-terminus: Val 43

蛋白结构(Molecular Characterization)

Precision Avi(Val 43 - Ile 300) NP_001766.2

This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag.

The protein has a calculated MW of 32.5 kDa. The protein migrates as 45-48 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

标记(Biotinylation)

Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.

蛋白标记度(Biotin:Protein Ratio)

The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

内毒素(Endotoxin)

Less than 1.0 EU per μg by the LAL method.

纯度(Purity)

>90% as determined by SDS-PAGE.

制剂(Formulation)

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Please see Certificate of Analysis for specific instructions.

For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

存储(Storage)

For long term storage, the product should be stored at lyophilized state at -20°C or lower.

Please avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:

  1. 4-8°C for 12 months in lyophilized state;
  2. -70°C for 3 months under sterile conditions after reconstitution.
 

电泳(SDS-PAGE)

Biotinylated Human CD38, His Tag (Cat. No. CD8-H82E7) SDS-PAGE gel

Biotinylated Human CD38, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

 

活性(Bioactivity)-ELISA

Biotinylated Human ELISA

Immobilized Anti-CD38 MAb, Human IgG1 at 5 μg/mL (100 μL/well) can bind Biotinylated Human CD38, His Tag (Cat. No. CD8-H82E7) with a linear range of 0.08-1.28 μg/mL (QC tested).

背景(Background)

CD antigen CD38 is also known as ADP-ribosyl cyclase 1, which belongs to the ADP-ribosyl cyclase family. CD38 is expressed at high levels in pancreas, liver, kidney, brain, testis, ovary, placenta, malignant lymphoma and neuroblastoma. CD38 is a multifunctional ectoenzyme that catalyzes the synthesis and hydrolysis of cyclic ADP-ribose (cADPR) from NAD+ to ADP-ribose. These reaction products are essential for the regulation of intracellular Ca2+. The loss of CD38 function is associated with impaired immune responses, metabolic disturbances, and behavioral modifications. The CD38 protein is a marker of cell activation. It has been connected to HIV infection, leukemias, myelomas, solid tumors, type II diabetes mellitus and bone metabolism. CD38 has been used as a prognostic marker in leukemia.
