  • Molecular Characterization
    Online(Ala 26 - Ala 158) Q62386-1

    This protein carries a polyhistidine tag at the N-terminus.

    The protein has a calculated MW of 15.8 kDa. The protein migrates as 18 kDa, 20-23 kDa and 26 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

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

    Contact us for customized product form or formulation.

  • 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.

  • Storage

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

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.

Human FcRn Heterodimer Protein Cell_Base

Mouse IL-17A, His Tag (Cat. No. CT8-M5240) stimulates secretion of IL-6 by NIH-3T3 cells. The ED50 for this effect is 2.132-5.005 ng/mL.

Protocol
  • Background
    Interleukin-17A (IL17A) is also known as cytotoxic T-lymphocyte-associated antigen 8 (CTLA8),which is a proinflammatory cytokine produced by activated T cells. IL17A can regulate the activities of NF-kappaB and mitogen-activated protein kinases. Also,IL17A can stimulate the expression of IL6 and cyclooxygenase-2 (PTGS2/COX-2), as well as enhance the production of nitric oxide (NO).Furthermore,IL17A has been found both in glycosylated and nonglycosylated forms. High levels of IL-17 are associated with several chronic inflammatory diseases including rheumatoid arthritis, psoriasis and multiple sclerosis.

ACROBiosystems治疗性抗体的功效不仅取决于Fab片段及其与靶抗原的结合活性,还取决于Fc片段及其与关键Fc受体的相互作用。Fc片段对FcRn的结合亲和力(FCGRT&B2M)将预测抗体的半衰期,而Fc片段与FcγRIIIa(CD16a)之间的结合亲和力将影响抗体引发ADCC的能力(抗体依赖性细胞介导的细胞毒性)。因此,必须在抗体工程化过程中针对一组受体测试候选人。ACROBiosystems提供了完整的重组Fc受体蛋白集合,包括它们的常见变体,以帮助您加快mAb的开发。
