This is a simple and fast protocol for the extraction of genomic DNA from Arabidopsis thaliana that works fine in PCR for simple amplicons. We only use this with (rosette) leaves but it is likely that ...

OverviewIn order to study spleen cells (e.g. lymphocytes granulocytes other immune cells) it helps to make single-cell suspensions so that the cells can be manipulated ex vivo easily. This protocol su ...

One of the uses of tamoxifen in the lab is the activation of enzymes deactivated via an estrogen-binding domain like Cre-ERT (Cre-LBD). Tamoxifen is an estrogen analogue that binds with higher affinit ...

PRIMARY MOUSE KERATINOCYTE CULTURESIsolation of epidermal keratinocytes from neonatal mice is based on the protocol of Dlugosz et al. Methods Enzymol. 254:3-20 (1995). The epidermis from a newborn mou ...

Setup You have yeast strains that are deficient in mating (eg Ste12 knockouts) and would like to test whether transforming them with a plasmid that contains genes that are supposed to complement the m ...

INTRODUCTION The Drosophila larval brain is a well-established model for investigating the role of stem cells in development. Neuroblasts (neural stem cells) must be competent to generate many thousan ...

Single-Cell Electroporation in XenopusXue Feng Liu and Kurt Haas INTRODUCTIONSingle-cell electroporation (SCE) is a versatile technique for delivering electrically charged macromolecules including DNA ...

SOS信号转导途径在植物离子平衡和耐盐中非常重要。SOS模型认为高Na+引起了胞内自由Ca2+的升高，激活了Ca2+结合蛋白编码的SOS3的表达，影响到下游的反应。SOS3激活了相连的SOS2（丝氨酸/苏氨酸蛋白激酶），SOS2/SOS3复合体调节盐忍耐因子编码的SOS1（质膜Na+/H+反向转运体）的表达水平，从而促使胞内过多的Na+排出体外。这其中涉及到K+的变化，Na+和K+平衡的破坏可能是 ...
