IL34Transfected / Overexpression Cell Lysate Product Information
Product Description:Human Cells transfected lysate in which Mouse IL-34 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.

Interleukin 34 (IL-34), also known as uncharacterized protein C16 or f77 homolog, is a secreted cytokine that belongs to unknown cytokine family. IL-34 protein is expressed in various tissues, including heart, brain, lung, liver, kidney, spleen, thymus, testes, ovary, small intestine, prostate and colon, and most abundant in the spleen. The colony-stimulating factor 1 receptor (CSF-1R) is identified as the receptor for IL-34. IL-34 increases growth or survival of immune cells known as monocytes. In addition, IL-34 promoted the formation of the colony-forming unit-macrophage (CFU-M), a macrophage progenitor, in human bone marrow cultures.
