Rat CD133 / PROM1 / Prominin 1 HEK293 Cell Lysate (WB positive control)

DatasheetSpecific ReferencesReviewsRelated ProductsProtocols
Rat PROM1 Transfected / Overexpression Cell Lysate Product Information
Expressed Host:Human Cells
Product Description:Human Cell lysate that Rat CD133 / PROM1 / Prominin 1 transfected / overexpressed for Western blot (WB) positive control. The whole cell lysate is provided in 1X Sample Buffer (1X modified RIPA buffer+1X SDS loading buffer).
Sequence information:A DNA sequence encoding the rat PROM1 (F1MAN1) (Asn171-Tyr424) was with the Fc region of mouse IgG1 at the N-terminus.
Predicted N Terminal:Asp
Molecule Mass:The recombinant rat PROM1 comprises 490 amino acids and predicts a molecular mass of 55.1 kDa. The apparent molecular mass of the recombinant protein is approximately 67 and 34 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Rat PROM1 Transfected / Overexpression Cell Lysate Usage Guide
Preparation Method:Cell lysate was prepared by homogenization in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
Lysis Buffer:Modified RIPA Lysis Buffer: 50 mM Tris-HCl pH 7.4, 150 mM NaCl, 1mM EDTA, 1% Triton X-100, 0.1% SDS, 1% Sodium deoxycholate, 1mM PMSF.
Quality Control Testing:12.5% SDS-PAGE Stained with Coomassie Blue after protein purification.
Stability:Samples are stable for up to twelve months from date of receipt.
Recommend Usage:1.  Centrifuge the tube for a few seconds and ensure the pellet at the bottom of the tube. 2.  Re-dissolve the pellet using 200μL pure water and boil for 2-5 min. 3. Store the lyophilized cell lysate at 4℃. After re-dissolution, recommend to aliquot it into smaller quantities and store at -80℃.
Storage Buffer:1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
Storage Instruction:Store at 4℃. After re-dissolution, aliquot and store at -80℃.
Application notes:Western blot (WB): Use at an assay dependent dilution.
Other Applications: Not tested.
Optimal dilutions/concentrations should be determined by the end user.
PROM1 Background

CD133, also known as PROM1 and Prominin 1, is a pentaspan transmembrane glycoprotein which belongs to the prominin family. It localizes to membrane protrusions and is often expressed on adult stem cells. CD133 is known to play a role in maintaining stem cell properties by suppressing differentiation. CD133 binds cholesterol in cholesterol-containing plasma membrane microdomains. It is proposed to play a role in apical plasma membrane organization of epithelial cells. CD133 is also involved in regulation of MAPK and Akt signaling pathways. Mutations in PROM1 gene have been shown to result in retinitis pigmentosa and Stargardt disease. PROM1 gene is expressed from at least five alternative promoters that are expressed in a tissue-dependent manner. Expression of this gene is also associated with several types of cancer.
