About this Antibody | |
Name | Recombinant Human Epigen (Recombinant Human Epigen; rHuEpigen);重組人Epigen |
Synonyms | EPGN |
Purity | >98% by SDS-PAGE and HPLC analyses. |
Biological Activity | Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using murine Balb/c 3T3 cells is less than 300ng/ml, corresponding to a specific activity of >3.3×103IU/mg. |
Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
Formulation | Lyophilized from a 0.2μm filtered concentrated solution in PBS, pH7.4. |
Endotoxin | Less than 1EU/μg of rHuEpigen as determined by LAL method. |
Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1% BSA to a concentration of 0.1-1.0mg/ml. Stock solutions should be apportioned into working aliquots and stored at ≤-20℃. Further dilutions should be made in appropriate buffered solutions. |
Category | Cytokine |
Background | Epigen is a member of the epidermal growth factor family and is expressed by several tissues, including the testis, liver, heart and in certain tumor cells. It is strongly mitogenic for fibroblasts and epithelial cells, despite its relatively weak affinity for its main receptor, ErbB1. The mitogenic potential of Epigen is enhanced by its unusually long persistence on the membrane before ubiquitylation and receptor-mediated depletion. The gene of human Epigen encodes a 154 amino acid (a.a.) residue type I transmembrane precursor glycoprotein which contains a 22a.a. signal peptide, an 88a.a. extracellular domain, a 21a.a. transmembrane domain and a 23a.a. cytoplasmic domain. By alternative splicing of the gene, Epigen has several isoforms. The mature, shed form of human Epigen (54-104a.a.) shares 92%, 94% and 94%a.a. sequence identity with mouse, rat and equine Epigen, respectively. |

保存條件:
???????-20℃或更低溫度保存,至少一年有效。由于蛋白的每次凍融均會引起部分失活,所以首次配制成相應(yīng)濃度的儲存液后(請根據(jù)產(chǎn)品簡介中Reconstitution一欄的信息配制儲存液),須分裝后-20℃或更低溫度凍存,以避免反復(fù)凍融。
注意事項:
???????由于有些塑料管壁對某些蛋白有較強的吸附作用,溶液中的蛋白很容易粘附在管壁上,并且粘附后的蛋白很難與管壁分離。而載體蛋白(Carrier protein,如0.1% BSA等)的主要作用是預(yù)先封閉塑料管壁上的蛋白結(jié)合位點,使細(xì)胞因子或重組蛋白不會粘附于管壁。所以一定要使用產(chǎn)品簡介中Reconstitution一欄的信息配制儲存液。
???????本產(chǎn)品僅限于專業(yè)人員的科學(xué)研究用,不得用于臨床診斷或治療,不得用于食品或藥品,不得存放于普通住宅內(nèi)。
???????為了您的安全和健康,請穿實驗服并戴一次性手套操作。
