Human Complement C5 Protein

产品信息(Product Info)
表达区间及表达系统(Source)

Recombinant Human Complement C5 Protein is expressed from HEK293 with His tag at the C-Terminus.
It contains Gln19-Cys1676 [Accession | P01031-1].

分子量大小(Molecular Weight)

Human Complement C5 Protein is cleaved into α chain and β chain by the enzyme lysis. Each chain has a predicted MW of 112.5 kDa (α chain) and 73.29 (β chain). Due to glycosylation, the protein migrates to 110-114 kDa (α chain) and 69-73 (β chain) based on Bis-Tris PAGE result.

纯度(Purity)

> 95% as determined by Bis-Tris PAGE
> 95% as determined by HPLC

内毒素(Endotoxin)

Less than 1EU per μg by the LAL method.

制剂(Formulation)

Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.

重构方法(Reconstitution)

Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.

存储(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.

产品数据(Assay Data)
Bis-Tris PAGE

Human Complement C5 on Bis-Tris PAGE under reduced condition. The purity is greater than 95%.

SEC-HPLC

The purity of Human Complement C5 is greater than 95% as determined by SEC-HPLC.

ELISA Data

Immobilized Human Complement C5, His Tag at 2μg/ml (100μl/well) on the plate. Dose response curve for Anti-Complement C5 Antibody, hFc Tag with the EC50 of 6.1ng/ml determined by ELISA (QC Test).

背景(Background)

Complement component 5 (C5) is an essential factor of the defensive complement system in all vertebrates.C5 plays a major role in complement activation; C5 convertase cleaves C5 into the pro-inflammatory C5a, and C5b, the nidus for the formation of the lytic membrane attack complex.

分子别名(Synonyms)

Complement C5; C5; CPAMD4; ECLZB; C5a; C5b; C5D

Note: HPLC results always come from liquid protein, due to absorption peak interference of trehalose in lyophilized powder.
