Description 

The PM5100 3-color Pre-Stained Protein Ladder High Range is a ready-to-use three-color protein standard with 14 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa in Tris-Glycine Buffer (9 to 235 kDa in Bis-Tris (MOPS) buffer and 10 to 235 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with different chromophores for easy identification of bands, with three reference proteins carrying enhanced intensity corresponding to a blue band at 20 kDa, green at 40 kDa, and red at 75 kDa, respectively, as separated on SDS-PAGE (Tris-Glycine buffer). The PM5100 3-color Pre-Stained Protein Ladder High Range is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins. 

Features

• Ready-to-use — Premixed with a loading buffer for direct loading, no need to boil.
• Three reference bands — 75 kDa (red), 40 kDa (green), and 20 kDa (blue)

Contents

Approximately 0.1~0.4 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2% SDS, 0.2 mM DTT, 3.6 M urea, and 15% (v/v) glycerol). 

Quality Control 

Under suggested conditions, PM5100 ExcelBand™ 3-color Pre-Stained Protein Ladder High Range resolves 14 major bands in SDS-PAGE (Tris-Glycine, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane. 

Storage

4°C for 3 months
-20°C for long term storage

Bacterial DNA Extraction Kit (Magnetic Beads)

The Bacterial DNA Extraction Kit (Magnetic Beads) was developed for the bacterial genomic DNA extraction from bacterial cultures directly using magnetic beads from a wide variety of gram-negative and gram-positive bacterial species, as well as yeast and other fungi. With our proprietary magnetic beads technology, the kit eliminates the tedious centrifuge steps for columns. The kit provides a reliable and simple approach for high-quality bacterial DNA isolation with fast magnetic response time and high binding capacity.

Bacteria are the most diverse and abundant small single-celled organisms and are vital to the planet’s ecosystems. Some bacterial species are pathogens that can cause a variety of diseases to humans and animals. Besides their ecological and biomedical importance, bacteria are also used in biotech and pharmaceutical applications such as production of enzymes, DNA preparation, biofuels, food research, and chemical production.

Bacterial cells are grown to log-phase and the culture is lysed directly with a lysis buffer, then mixed with beads to bind genomic DNA. After wash steps, genomic DNA is eluted in Low TE or TE Buffer. The isolated genomic DNA with the magnetic beads is free of contamination such as RNA, proteins, salts, and other impurities. Bacterial DNA extracted using the kit is suitable for downstream applications such as qPCR, PCR, DNA sequencing, Southern Blotting, molecular cloning, DNA hybridization, restriction enzymatic digestion, and Next-generation Sequencing (NGS) etc.

Features

• 100% centrifuge-free
  • Bacterial cultures can be used directly without centrifuge to pellet the bacteria
• Simple magnetic beads method
  • No centrifuge needed
  • No column needed
  • No vacuum needed

Purified genomic DNA from various bacteria were isolated with the Bacterial DNA Extraction Kit. A portion of the extracted genomic DNA was loaded on a 1% agarose gel. DNA ladder: BioDynami 1 kb Plus DNA Ladder (Cat.# 10005L).
