PIK3IP1Transfected / Overexpression Cell Lysate Product Information
Product Description:Human Cells transfected lysate in which Human PIK3IP1 has been over-expressed. The whole cell lysate is provided in 1X Sample Buffer (1X modified RIPA buffer+1X SDS sample buffer).
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 with Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 minutes in 1 x SDS sample 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
Stability:Samples are stable for up to twelve months from date of receipt at -80℃
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 boiled for 2-5 min. 3. Store it at -80℃. Recommend to aliquot the cell lysate into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles. Notes:The lysate is ready to load on SDS-PAGE for Western blot application. If dissociating conditions are required, add reducing agent prior to heating.
Storage Buffer:In modified RIPA Lysis Buffer
Storage Instruction:Store at -80℃. Aliquot to avoid repeated freezing and thawing
Application notes:WB: Use at an assay dependent dilution.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.

PIK3IP1 contains 1 kringle domain and is a negative regulator of phosphatidylinositol-3-kinase (PI3K), suppresses the development of hepatocellular carcinoma. PI3K is a well-known regulator of cell division, motility, metabolism and survival in most cell types. Proper liver function and development highly depend on intact PI3K signal transduction. Aberrant PI3K pathway signaling in the liver is associated with hepatocellular carcinoma. PI3K signaling is involved in the homeostasis of lipid and glucose metabolism. Activation of the PI3K pathway induces lipogenesis and glycogenesis in the liver, since both Akt overexpressing transgenic mice and PTEN knockout mice develop fatty liver and hypoglycemia. PIK3IP1 overexpression can contribute to glucose homeostasis and fatty deposition.
