Recombinant Human UPA/PRAP1

Recombinant Human UPA/PRAP1  (CA24)

 

产品说明(Description)

Recombinant Human Proline-Rich Acidic Protein 1 is produced by our Mammalian expression system and the target gene encoding Val21-Gln151 is expressed with a 6His tag at the C-terminus. 

Accession #: AAL16670.1

Known as: Proline-Rich Acidic Protein 1; Epididymis Tissue Protein Li 178; Uterine-Specific Proline-Rich Acidic Protein; PRAP1; UPA

 

制剂（Formulation）

Lyophilized from a 0.2 μm filtered solution of 20mM PB,150mM NaCl,pH7.4.

 

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）

Proline-rich acidic protein 1, also known as Uterine-specific proline-rich acidic protein, UPA and PRAP1, is a secreted protein. PRAP1 is abundantly expressed in the epithelial cells of the liver, kidney, gastrointestinal tract and cervix. PRAP1 is up-regulated by butyrate, trichostatin A and 5'-aza-2' deoxycytidine. PRAP1 may play an important role in maintaining normal growth homeostasis in epithelial cells. PRAP1 is suppressed through epigenetic mechanisms involving histone deacetylation and methylation. PRAP1 has been shown to cause cell growth inhibition in cancer cell lines.
