Product Description

Details

  • Powerful lysis - Optimized bead beating method enables efficient lysis and solubilization of total nucleic acids and cellular proteins from fungi
  • Easy and fast method - Novel spin filter-based method enables sequential DNA, RNA and protein extraction in less than 40 minutes without the need for precipitation
  • Accurate results – Nucleic acids can be used in PCR, qPCR, RT-PCR, and next-generation sequencing; protein can be used for mass spectrometry, 1D and 2D gel electrophoresis

The AllPrep Fungal DNA/RNA/Protein Kit is designed to isolate total nucleic acids and cellular proteins from fungal cultures in a user-friendly spin column format.  An optimized bead beating method enables efficient lysis and solubilization of nucleic acids and proteins from diverse fungal species. The use of silica spin columns to achieve reversible, sequential immobilization of DNA, RNA and proteins greatly streamlines the nucleic acid and protein isolation process, enabling direct correlations between genes, their expression, and function. Isolated nucleic acids (gDNA, rRNA, mRNA, small RNAs) are suitable for the most demanding downstream applications including PCR, qPCR, RT-PCR, and next-generation sequencing (NGS). Purified proteins are suitable for 1D SDS-PAGE and mass spectroscopy following in-gel trypsin digestion. Some applications, including 2D SDS-PAGE and solution phase proteolytic digestion for mass spectrometry, may require an additional detergent removal step following protein elution. 

This novel sequential isolation method begins with mechanical lysis of cultured fungal cells using a 0.5 mm glass bead tube. Nucleic acids and proteins are completely solubilized during homogenization and mixed with a DNA binding solution. DNA is bound to a spin column and the flow-through containing RNA and proteins is then combined with a solution that binds total RNA on a second spin column. The final flow-through, containing denatured proteins, is combined with another novel buffer to immobilize the proteins onto the third and final silica spin column. Each spin column containing either immobilized nucleic acids or proteins is then washed and the immobilized analyte is eluted.

Figure 1. Sequential spin filter binding captures and concentrates DNA (1), RNA (2) and proteins (3) in lysate from fungal cultures. 1 mL of overnight cultures were processed using the AllPrep Fungal DNA/RNA/Protein Kit. Nucleic acids were eluted in 100 μl of their respective elution reagent. For (3), proteins were eluted in 100 μl of 1% SDS/HEPES elution buffer. 10 μl of each sample was run on a Bio-Rad Any kD™ Mini-PROTEAN TGX Stain-Free™ Gel for 25 minutes at 200V. Gels were stained using SimplyBlue SafeStain. A: C. albicans; B: C. glabrata; C: C. tropicalis; D: S. cerevisiae, brewing strain 1; E: S. cerevisiae, brewing strain 2
 
 
 
Figure 2. Successful 2D SDS PAGE analysis of C. albicans proteins extracted using the AllPrep Fungal DNA/RNA/Protein Kit. 1 ml of overnight culture was processed using the AllPrep Bacterial DNA/RNA/Protein Kit. Eluent was run, without modification, on a pH 4-8 IEF gradient and 10% acrylamide slab gel using an SDS-compatible carrier ampholine (CA). Molecular weight standards (220,000, 94,000, 60,000, 43,000, 29,000, and 14,000). 2D analysis was performed by Kendrick Labs, Madison, WI.
 
 
 
Figure 3. Equivalent mass spectrometry (MS) results with the AllPrep Fungal DNA/RNA/Protein Kit and conventional protein extraction methods. The AllPrep Fungal DNA/RNA/Protein Kit was compared against a conventional protein extraction method, sodium carbonate, via MS. C. albicans cells were resuspended in sodium carbonate and subjected to bead beating. The crude, unpurified lysate was run alongside isolates processed using the AllPrep Fungal DNA/RNA/Protein Kit. 20 μg of protein isolate was run on a Bio-Rad Any kD™ Mini-PROTEAN TGX Stain-Free™ Gel for 25 minutes at 200V. The gel was stained using SimplyBlue SafeStain and the section contained within the indicated square was excised and analyzed by MS (A). Identified proteins with >4 peptide matches were classified using PANTHER version 10. The results indicated comparable protein class isolation between both samples (B).
