■Introduction

RayBio® Phospho-Chk1 (Ser280) ELISA kit is a very rapid, convenient and sensitive assay kit that can monitor the activation or function of important biological pathways in human cell lysates. By determining phosphorylated Chk1 protein in your experimental model system, you can verify pathway activation in your cell lysates. You can simultaneously measure numerous different cell lysates without spending excess time and effort in performing a Western Blotting analysis.

This Sandwich ELISA kit is an in vitro enzyme-linked immunosorbent assay for the measurement of human phospho-Chk1. An anti-pan Chk1 antibody has been coated onto a 96-well plate. Samples are pipetted into the wells and Chk1 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and rabbit anti-Chk1 (Ser280) antibody is used to detect phosphorylated Chk1. After washing away unbound antibody, HRP-conjugated anti-rabbit IgG is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Chk1 (Ser280) bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Protocol Outline

■Typical Data

Positive Control

HeLa cells were treated with Calyculin A. Solubilize cells at 4 x 10^7 cells/ml in Cell Lysate Buffer. Serial dilutions of lysates were analyzed in this ELISA. Please see step 3 of Part VI Reagent Preparation for detail.

Calyculin A Stimulation of HeLa Cell Lines

HeLa cells were treated or untreated with Calyculin A. Cell lysates were analyzed using this phosphoELISA and Western Blot.

■Storage/Stability

Upon receipt, the kit should be stored at –20°C. Please use within 6 months from the date of shipment. After initial use, Wash Buffer Concentrate (Item B), Assay Diluent (Item E), TMB One-Step Substrate Reagent (Item H), Stop Solution (Item I) and Cell Lysate Buffer (Item J) should be stored at 4°C to avoid repeated freeze-thaw cycles. Return unused wells to the pouch containing desiccant pack, reseal along entire edge, and store at –20°C. Item D, store at 2-8°C for up to one month (store at -20°C for up to 6 months, avoid repeated freeze-thaw cycles). Reconstituted Positive Control (Item K) should be stored at -70°C.
