The Human PS2 (Presenilin 2) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human PS2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Human PS2 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Human PS2, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human PS2. You can calculate the concentration of Human PS2 in the samples by comparing the OD of the samples to the standard curve.

A Vision of Pastoring That is Rare but Inspiring
Format: Kindle
No one has been more helpful to me from afar in church planting and pastoring than Eugene Peterson. His vision of pastoring is inspiring but increasingly rare in the church growth landscape of the Evangelical industrial complex. “The pastors of America have metamorphosed into a company of shopkeepers, and the shops they keep are churches. They are preoccupied with shopkeeper’s concerns—how to keep the customers happy, how to lure customers away from competitors down the street, how to package the goods so that the customers will lay out more money.” In this book, Peterson offers up an alternate view—a biblical view—of the work of the pastor: prayer, reading Scripture, and offering spiritual direction. This work is modest work—hard work—but it is the good work God has called us to.

Excellent
Format: Kindle
An excellent work on the essential shape of pastoral work. A very convicting and important read for those who work in ministry- prayer, scripture, and spiritual direction will never be demanded of us, but are non-negotiable in order to maintain our call.

A must read for any pastor or spiritual leader
Format: Paperback
This book is profoundly insightful and easy to read and understand. It is not heavily theological (and does not need to be). It is practical. I have purchased an additional copy to give my pastor for his birthday. If he has already read it, he can pass it on. EVERY pastor needs to read this and practice these tips, which many do not receive in seminary. THIS is the type of pastor I want and need (and my pastor does embody much of what Peterson describes). I think pastors should read this every year or two to reassess their progress toward keeping these goals always in mind and in practice as much as possible.

A still timely writing for all pastors
Format: Paperback
Although first published 25 years ago, Peterson addresses a matter that is still timely, the need for all pastors to commit themselves to prayer, reading scripture and spiritual direction. These, Peterson asserts, are an essential foundation for all other aspects of ministry. Peterson's premise, that many pastors have abdicated their primary calling to these three practices, is still very relavent to the current state of pastoral ministry. Its content will be useful for new and veteran pastors alike.
