This protocol contains methods for pulling microinjection needles using two different models of pipette pullers. The advantage of pulling needles in the laboratory is that a variety of different needle types can be pulled, depending on the samples and cells being injected. An added advantage is cost; once a pipette puller has been purchased, boxes of glass capillaries are inexpensive compared to premade microinjection needles. - [Read Preparation (Pulling) of Needles for Gene Delivery by Microinjection Protocol]
This protocol is not phenol-based, but does require the addition of chloroform. The Concert Plant Reagent is intended for the isolation of RNA from a wide variety of plant tissues including blue spruce needles, potato tuber etc. - [Read Purification of RNA from Plant Tissue Using the Concert Plant Reagent]
