Description 

YesBlot™ Western Marker I is a ready-to-use mixture with ten IgG-binding proteins covering a wide range of molecular weights from 15 to 200 kDa in Tris-Glycine buffer. YesBlot™ Western Marker I performs dual functions. First, it contains 4 pre-stained proteins (10, 25, 45 and 70 kDa) for monitoring protein separation during SDS-PAGE, verification of Western transfer efficiency on membranes (nitrocellulose, PVDF, or nylon) and for approximating the protein size. Second, ten IgG-binding proteins can be immuno-detected on film or by CCD imaging. YesBlot™ Western Marker I is compatible for chemiluminescent, fluorescent, chromogenic or other detection systems. In addition, YesBlot™ Western Marker I has two reference bands with enhanced intensity (at 30 kDa and 80 kDa). The marker is supplied in the gel loading buffer and is ready to use. Do NOT heat, dilute, or add reducing agents before loading. 

Features

• Direct visualization — 10 IgG-binding proteins for direct visualization on Western blots
• Pre-stained bands — 4 prestained proteins for monitoring protein separation during electrophoresis and Western blotting transferring efficiency on membrane
• Wide range — 10 clear bands from 15 to 200 kDa for size estimation
• Quick reference — two enhanced bands (30 and 80 kDa)

Contents 

The YesBlot™ Western Marker I contains recombinant IgG binding proteins, prestained recombinant proteins, glycerol and SDS. 

Storage

4°C for 3 months
-20°C for 24 months

Principle

This product is based on silica gel purification. The sample is lysed and digested with lysate and protease, DNA / RNA is released into the lysate. Transfer to an adsorption plate and filter column. DNA/RNA is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, DNA / RNA was finally eluted with low-salt buffer (10 Mm Tris, pH 8.0).

Advantages

• Fast – several samples can be extracted in 20 minutes by column method
• High quality – high purity total RNA can be directly used in various sensitive downstream applications
• Safe – no phenol chloroform extraction required
• Sensitive – DNA/RNA can be recovered at the level of PG
• High yield – carrier RNA contained in the product maximize the recovery of trace nucleic acid

Storage and Stability

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