C22-100-04 Perfemiker rHu Her2 | 重组人 Her2/ERBB2 蛋白
Recombinan Human Her2/ERBB2 Protein

Gene Name Synonym:
CD340; ENV; ENVW; ERVWE1; HER-2; HER-2/neu; HER2; HERV-7q;HERV-W-ENV; HERV7Q; HERVW; HERVWENV; MLN 19; MLN19; NEU;NGL; TKR1

纯度:> 90 % as determined by SDS-PAGE
内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
表达宿主:HEK293 Cells
种属:Human
预测 :N 端Thr 23
分子量:The recombinant human ErbB2 comprises 641 amino acids and has a calculated molecular mass of 71 kDa. As a result of glycosylation, rh ErbB2 migrates as an approximately 100-110 kDa protein in SDS-PAGE under reducing conditions.
生物活性
1. Measured by its binding ability in a functional ELISA.
Immobilized human Erbb2 at 2.5 μg/ml (100 μl/well) can bind Herceptin with a linear range of 1.28-32 ng/ml.
2. Measured by its ability to block anti-ErbB2 mediated inhibition of BT474 human breast ductal carcinoma cell proliferation. The ED50 for this effect is 0.2-1 μg/mL in the presence of 0.6 µg/mL Anti-ErbB2/Her2 Monoclonal Antibody.
3. Using the Octet RED System, the affinity constant (Kd) of Her2 / ERBB2 Protein, Human, Recombinant (His Tag) (Cat: 10004-H08H) bound to Pertuzumab was 0.1 nM.
蛋白构建:
A DNA sequence encoding the extracellular domain (Met 1-Thr 652) of human ErbB2 (NP_004439.2) was fused with the polyhistidine tag at the C-terminus.
缓冲液:
Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式:
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件:
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶:
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

外观:Sterile Filtered White lyophilized (freeze-dried) powder.
纯度:> 95 % by SDS-PAGE and HPLC analyses
内毒素:Less than 1 EU/µg of rHuIL-17 as determined by LAL method.


生物活性:
Fully biologically active when compared to standard. The ED50 as determined by inducing IL-6 secretion of murine NIH/3T3 cells is less than 7.5 ng/ml, corresponding to a specific activity of > 1.3 × 105 IU/mg.

Formulation:

Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.

运输方式

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

稳定性 & 储存条件

Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
- 12 months from date of receipt, -20 to -70 °C as supplied.
- 1 month, 2 to 8 °C under sterile conditions after reconstitution.
- 3 months, -20 to -70 °C under sterile conditions after reconstitution.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in 4 mM HCl to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

Usage
This material is offered only for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE.
