Recombinant Human SMAD1

Recombinant Human SMAD1 (CE81)

 

产品说明(Description)

Recombinant Human Mothers Against Decapentaplegic Homolog 1 is produced by our E.coli expression system and the target gene encoding Met1-Ser465 is expressed with a GST tag at the N-terminus. 

Accession #: Q15797

Known as: Mothers Against Decapentaplegic Homolog 1; MAD Homolog 1; Mothers Against DPP Homolog 1; JV4-1; Mad-Related Protein 1; SMAD Family Member 1;Transforming Growth Factor-Beta-Signaling Protein 1; BSP-1; SMAD1; BSP1; MADH1;SMAD 1;Smad1;hSMAD1;MADR1

 

制剂（Formulation）

Lyophilized from a 0.2 μm filtered solution of 20mM TrisHCl, 150mM NaCl, pH 8.0 .

 

质量控制（Quality Control） 

 

Purity:            Greater than 95% as determined by reducing SDS-PAGE.    

Endotoxin:    Less than 0.1 ng/ug (1 EU/ug) as determined by LAL test.

 

复溶（Reconstitution）

Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.    

 

保存（Storage）

Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.Reconstituted protein solution can be stored at 4-7°C for 2-7 days.Aliquots of reconstituted samples are stable at < -20°C for 3 months.    

 

背景（Background）

SMAD Family Member 1 (SMAD1) is a member of the dwarfin/SMAD family. SMAD1 has the highest expression in the heart and skeletal muscle, containing one MAD homology 1 domain and one MAD homology 2 domain, As a transcriptional modulator SMAD 1 is activated by bone morphogenetic proteins type 1 receptor kinase. Defects in SMAD1 may cause primary pulmonary hypertension (PPH1), characterized by plexiform lesions of proliferating endothelial cells in pulmonary arterioles. The lesions lead to elevated pulmonary arterial pression, right ventricular failure and death.
