Biotinylated Human IgE Protein (IGE-HM401B) Summary
Product Description |
Recombinant Biotinylated Human IgE Protein is expressed from HEK293 with His and Avi tag at the C-Terminus.It contains Cys209-Lys428. |
Product Background |
Immunoglobulin E (IgE) is well known for its role in allergic disease, the manifestations of which are mediated through its two Fc receptors, FcεRI and CD23 (FcεRII). IgE and its interactions with these receptors are therefore potential targets for therapeutic intervention, and exciting progress has been made in this direction. Furthermore, recent structural studies of IgE-Fc, the two receptors, and of their complexes, have revealed a remarkable degree of plasticity at the IgE-CD23 interface and an even more remarkable degree of dynamic flexibility within the IgE molecule. |

Formulation |
Lyophilized from 0.22 um filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization. |
Reconstitution |
Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking. |
Stability And Storage |
-20 to -80°C for 12 months as supplied from date of receipt.;-80°C for 3 months after reconstitution.;Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles. |
