Human NEU2 HEK293 Overexpression Lysate


Human NEU2 HEK293 Overexpression Lysate: 产品信息

This Human NEU2 overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of NEU2 protein (Cat: 15845-H08H) from the overexpression lysate was verified.
HEK293 Cells
A DNA sequence encoding the human NEU2 (CAB41449.1) (Met1-Gln380) was expressed with a polyhistidine tag at the C-terminus.
The recombinant human NEU2 consists 391 amino acids and predicts a molecular mass of 43.7 kDa.

Human NEU2 HEK293 Overexpression Lysate: 使用指南

Cell lysate was prepared by homogenization of the over-expressed cells 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.
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.
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.
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
稳定性 & 储存条件
Store at 4℃ for up to twelve months from date of receipt. After re-dissolution, aliquot and store at -80℃ for up to twelve months. Avoid repeated freeze-thaw cycles.
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

Human SIAL2 Overexpression Lysate

NEU2 背景信息

Human sialidase 2 (NEU2) is a cytoplasmic sialidase that degrades sialyl glycoconjugates, including glycoproteins and gangliosides, via hydrolysis of terminal sialic acids to produce asialo-type molecules. It belongs to a family of glycohydrolytic enzymes that remove sialic acid residues from glycoproteins and glycolipids. NEU2 expression as assessed by quantitative real-time PCR was found to be extremely low or undetectable in many human tissues and cells, with notable exceptions like the placenta and testis. The human cytosolic sialidase NEU2 is the only mammalian enzyme structurally characterized and represents a valuable model to study the specificity of novel NA inhibitory drugs. Diseases associated with NEU2 include Galactosialidosis and Discrete Subaortic Stenosis.
