The PM2600 ExcelBand™ 3-color High Range Protein Marker is a ready-to-use three-color protein standard with 12 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 a blue chromophore except for two reference bands (one green and one red band at 25 kDa and 75 kDa respectively) when separated on SDS-PAGE (Tris-Glycine buffer). The PM2600 3-color High Range Protein Marker 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.
Two reference bands — 75 kDa (red) and 25 kDa (green)
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, PM2600 ExcelBand™ 3-color High Range Protein Marker resolves 12 major bands in 15% SDS-PAGE (Tris-Glycine buffer, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane.
Storage
4°C for 3 months -20°C for long term storage

Introduction
The Kit is designed for purification of total RNA, including miRNA and other small RNA molecules (18nt), from cultured cells and various animal and human tissues, including difficult-to-lyse tissues samples. Alternatively, a miRNA-enriched fraction and a total RNA (>200nt) fraction can be purified separately. This Kit combines phenol/guanidine-based lysis of samples and silica membrane–based purification of total RNA. MagZol Reagent, included in the kits, is a monophasic solution of phenol and guanidine thiocyanate, designed to facilitate lysis of tissues, to inhibit RNases, and also to remove most of the cellular DNA and proteins from the lysate by organic extraction.

Main Functions
Isolation miRNA and other small RNA molecules(18nt), from cultured cells and various animal and human tissues, using MagZol reagent and column
Applications
RT-PCR, Northern Blot, poly A+purification, nucleic acid protection and in vitro translation
Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such asguanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein andother impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.
This kit combines acid/guanidine (MagZol) extraction technology with glass fiber filter membrane purification, which can improve the extraction effect of complex samples and samples with low RNA content. After the sample is treated with MagZol reagent and chloroform, the supernatant is added with ethanol to provide appropriate binding conditions, then transferred to the purification column and centrifuged. Macromolecular RNA can be efficiently bound to the membrane. Collect the filtrate containing small RNA, add more ethanol to adjust the binding capacity of small RNA, the pollutants can be efficiently washed away by second cleaning. Finally, the purified RNA was eluted by RNase free water.
Advantages
High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
Fast – several samples can be extracted in 40 minutes
High applicability – samples including animals, plants, bacteria, cells, etc.
High concentration – efficiently remove macromolecular RNA, enrich small RNA and improve sensitivity

Storage and Stability
MagZol Reagent should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect its performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
