Human CAMKIV Baculovirus-Insect Overexpression Lysate 产品信息
Product Description
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.
Expression Host
Baculovirus-Insect Cells
Sequence Information
A DNA sequence encoding the human CAMK4 (NP_001735.1) (Met 1-Tyr 473) was fused with the GST tag at the N-terminus.
Molecule Mass
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 Usage Guide
Preparation Method
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.
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.
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.
Sample Buffer
1 X Sample Buffer (1 X modified RIPA buffer+1 X SDS loading buffer).
Stability & Storage
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.
Application
Western Blot (WB)
Optimal dilutions/concentrations should be determined by the end user.

CAMKIV Background Information
Ca 2+/ calmodulin-dependent protein kinase 4 (CAMKⅣ) belongs to the serine/threonine protein kinase family, and to the Ca 2+/calmodulin-dependent protein kinase subfamily which is widely recognized as an essential enzyme implicated in the phophoinositide amplification cascade. Ca 2+/calmodulin dependent protein kinase (CAMK) can be activated by the introcellular increased Ca 2+ and then apt to combine with the target protein. Ca 2+/ 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.
Full Name
