  • Molecular Characterization
    Online(Gln 22 - Pro 152) Q6ISS4-1

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

    The protein has a calculated MW of 17.8 kDa. The protein migrates as 25-28 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Biotin:Protein Ratio
    The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by reduced 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.

Protocol
  • Background
    Leukocyte-associated immunoglobulin-like receptor 2 (LAIR2) is also known as CD antigen CD306. LAIR2 contains one Ig-like C2-type (immunoglobulin-like) domain. LAIR2 is a member of the immunoglobulin superfamily and was identified by its similarity to LAIR1, an inhibitory receptor present on mononuclear leukocytes. LAIR2 / CD306 is thought to be secreted and may help modulate mucosal tolerance.

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。
