Human TGM2 Transfected / Overexpression Cell Lysate Product Information
Expressed Host:Baculovirus-Insect cells
Product Description:Baculovirus-Insect Cell lysate that Human TGM2 / TGC / Transglutaminase-2 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 human TGM2 (NP_004604.2) (Met 1-Ala 687) was expressed, with a polyhistidine tag at the N-terminus.
Predicted N Terminal:His
Molecule Mass:The recombinant human TGM2 consists of 705 amino acids and has a predicted molecular mass of 79.6 kDa. It migrates as an approximately 80 kDa band in SDS-PAGE under reducing conditions as estimated.
Human TGM2 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.
TGM2 / Transglutaminase 2 Background

Protein-glutamine gamma-glutamyltransferase 2, also known as Tissue transglutaminase, Transglutaminase C, Transglutaminase-2, and TGM2, is a member of the transglutaminase superfamily. TGM2 plays a role in cell growth and survival through the anti-apoptosis signaling pathway. It is a calcium-dependent acyltransferase which also undergoes a GTP-binding/GTPase cycle even though it lacks any obvious sequence similarity with canonical GTP-binding (G) proteins. TGM2 is a multi-functional protein which catalyzes transamidation reactions or acts as a G-protein in intracellular signalling. As an enzyme which is responsible for the majority of transglutaminase (TG) activity in the brain, TGM2 is likely to play a modulatory role in nervous system development and has regulatory effect on neuronal cell death as well. Most importantly, numerous studies have presented data demonstrating that dysregulation of TGM2 may contribute to the pathogenesis of many neurodegenerative disorders, including Huntington's disease, Alzheimer's disease, Parkinson's disease and amyotrophic lateral sclerosis as well as nervous system injuries.
