Human CAMKIV Baculovirus-Insect Overexpression Lysate: 製品の情報
This Human CAMKIV overexpression lysate was created in Baculovirus-Insect Cells and intented for use as a Western blot (WB) positive control. Purification of CAMKIV protein (Cat: 10664-H09B) from the overexpression lysate was verified.
A DNA sequence encoding the human CAMK4 (NP_001735.1) (Met 1-Tyr 473) was fused with the GST tag at the N-terminus.
The recombinant human CAMK4/GST chimera consists of 697 amino acids and has a predicted molecular mass of 79 kDa. It migrates as an approximately 100 kDa band in SDS-PAGE under reducing conditions.
Human CAMKIV Baculovirus-Insect Overexpression Lysate: 用法
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.
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).
安定性 & 保存条件
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.

Ca2+/ calmodulin-dependent protein kinase 4 (CAMKⅣ) belongs to the serine/threonine protein kinase family, and to the Ca2+/calmodulin-dependent protein kinase subfamily which is widely recognized as an essential enzyme implicated in the phophoinositide amplification cascade. Ca2+/calmodulin dependent protein kinase (CAMK) can be activated by the introcellular increased Ca2+ and then apt to combine with the target protein. Ca2+/ calmodulin-dependent protein kinase 4 (CAMKⅣ) is a multifunctional CaM-dependent kinase protein with limited tissue distribution, that has been implicated in transcriptional regulation in lymphocytes, neurons and male germ cells. All of the isforms of this family, including myosin light chain kinase, phosphorylase kinase, CaMK1, CaMKⅢ and CaMKⅣ have EF-hand structure.
