Benefits of Using the Page Ruler Prestained Protein Ladder

Ideally, a protein ladder is an important tool for determining the sizes of proteins (or other macromolecules) in any sample. By comparing the banding pattern to that of a known molecular weight marker such as Page Ruler Prestained Protein Ladder, laboratory researchers can easily quantify and size the sample proteins accurately. Here are some key benefits of using this product:

1. High Accuracy:

The Page Ruler Prestained Protein Ladder contains 10 bands that range from 6-245 kDa with 16 dye colours across these bands which allow for exact identification of molecular weights without compromising precision or accuracy. It helps generate fast, reproducible results every time for reliable quantitative measurements and set up a powerful reference point for your lab work.

2. Easily Visible Bands:

The bands on the protein ladder are pre-stained to enable highly accurate visualization even through ultraviolet light sources or trans-illumination techniques with high sensitivity DNA gels and western blots loaded with numerous samples per lane. The pre-stained format eliminates any potential staining errors when working with gels and membranes containing multiple samples on it, providing excellent results without having to manually stain each sample prior loading.

3. Time Saving:

Using Page Ruler pre-stained protein ladders during Western blotting or sizing experiments not only expedites the experimental procedures but also reduces labor intensive processes associated with conventional protein markers such as SDS PAGE assays – essentially saving hours of time per experiment which would have been consumed if traditional ladders had been used instead.

4 Cost Effective:

This prestained ladder is economical and cost effective when compared to other protocols as its convenient format doesn’t require large amounts reagents nor long run times typically involve in staining small molecular weight marker proteins after running a gel separately before analysing them on western blotting platform alongside other samples being tested simultaneously in a single analysis run by commonly used laboratory equipment thus reducing the cost associated

Step-by-Step Guide to Using the Page Ruler Prestained Protein Ladder

The Page Ruler prestained protein ladder is a useful tool for measuring the sizes of proteins. It is frequently used in analytical laboratories such as food testing and research, where the size of proteins need to be accurately determined and quantified. To ensure accurate results, it’s important to follow the instructions carefully when using this ladder. The following steps will help you get started on using the Page Ruler prestained protein ladder.

Step 1: Prepare your samples

Before you can begin using the Page Ruler prestained protein ladder, you must prepare your samples according to their specific requirements. Depending on what size range of proteins you are looking for, your sample preparation may include solubilizing and concentrating it into a stream or in an appropriate buffer solution. Additionally, any necessary surface treatments should also be done before loading onto the gel electrophoresis system.

Step 2: Load your samples onto the gel

Once your sample preparation is complete, load them onto an agarose gel with a suitable voltage and pre-determined times and conditions for electrophoresis — which depend largely upon how much sample material is present in total volume. Make sure that each well in the gel has an equal amount of sample before beginning electrophoresis so that all data has good baseline comparison points later on during analysis of results.

Step 3: Set up apparatus with running buffer solution

Now it’s time to set up your apparatus with running buffer solution according to manufacturer’s specifications provided on their product page or instruction manual — typically, gel boxes equipped with power units and tanks for exchanging gels are best for stability but vertical models have been known to give sufficient results too if space savings or convenience comes into play at all over capacity or reliability needs… With everything set up securely, fill any empty tank bottoms or reservoirs with buffer solution (deionized water works great) ensuring all surfaces come properly wetted from bottom up — ideally

Commonly Asked Questions (FAQs) About using the Page Ruler Prestained Protein Ladder

What is the Page Ruler Prestained Protein Ladder?

The Page Ruler Prestained Protein Ladder is a 10-lane protein ladder designed for use with SDS polyacrylamide gels. It can be used to accurately assess the size of proteins or peptides in a sample as well as identify protein subunits and/or degradation products. The ladder has 10 different protein markers ranging from 12.5 to 250 kDa, including lower-molecular weight bands that are more common in native PAGE gels. The lanes contain 0.5 ml each of prestained proprietary mixture of “ready-to-use” proteins as well as glycerol and EDTA, which helps to improve resolution on native gels. It also features blue dye for easier visualization and an expiration date for quality assurance purposes.

Can I store any unused portions of the gel after use?

Yes, any remaining portion of the prestained protein ladder can be stored at 4°C in the dark for up to one month from opening the package, provided that it is still sealed and stored according to manufacturer specifications. It is important to remember that repeated freeze/thaw cycles should be avoided as they may lead to loss of activity or reduced product performance over time.

How do I prepare the Page Ruler Prestained Protein Ladder for use?

To prepare your ladder for use, simply denature it by boiling in sample buffer containing 2% SDS plus dithiothreitol (DTT) equivalent weight). Boil the samples at 95°C until they become clear; this usually takes 1-2 minutes depending on sample concentration. Once denatured, you can immediately proceed with loading onto a precast or homemade gel system and applying an electric field using electrophoresis techniques as appropriate per your lab procedures and protocols.
