Protein A magnetic microspheres

Product Overview

Protein A magnetic beads are a special biotechnology product commonly used in immunoprecipitation (IP) experiments in biomedical research. They are made of superparamagnetic material coated with Protein A, a protein isolated from Staphylococcus aureus that specifically binds the Fc fragment of several mammalian IgGs.

 

Technical Parameter

Concentration: 30 mg/mL

Solvent: water

Diameter: ~1um

SPA load : 70-75ug/mg

Surface potential:~ 29 mV

Magnetic content: 35%-45%

 Product Features

 

High affinity: Protein A magnetic beads are able to bind specifically to Fc fragments of a wide range of mammalian IgGs with high affinity. 

Superparamagnetic: These magnetic beads are made of superparamagnetic material, which can be rapidly magnetised and show magnetic properties under an applied magnetic field, facilitating experimental manipulation and separation. 

Low non-specific binding: Protein A magnetic beads are usually pre-closed to reduce non-specific binding and improve the specificity and reproducibility of experiments. 

High capacity: Protein A magnetic beads have a high binding capacity and can capture a large number of antibodies or antigens.


Application Fields

Application Fields

 

Immunoprecipitation assays: In cell lysates, the specific binding ability of Protein A magnetic beads allows for the capture of protein complexes bound to their antibodies for downstream analyses such as protein blotting (Western Blot) or mass spectrometry. 

Antibody purification: Due to the high affinity of Protein A for IgG, Protein A magnetic beads can be used to purify specific types of antibodies from mixed samples. 

Affinity Chromatography: In affinity chromatography, Protein A magnetic beads can be used as a solid phase carrier for the separation and purification of target proteins.

Beyond my expectations
Size: 10 Wide, Color: Mocha Grainy Leather
Really nice shoes. Wide enough and comfortable I’m keeping these.

Good Fit Out of the Box
Size: 9, Color: Black
The shoes came with the correct size and is a good fit. They were originally pretty stiff, but are much better now after breaking them in. They look good. but as other's have said, they are made of synthetic leather and in my opinion have kind of a plastic look to them. The quality is good with ridged rubbber soles. I thought they were kind of expensive, but then again I haven't purchased these type of shoes in a while. A family member told me that if they were real leather, they would have been a lot more expensive. For what the shoes are I would recommend the purchase.

Sleek and classy loafer
Size: 10.5, Color: Black
Was skeptical on this purchase but I have to say, well worth it. Not super expensive but very comfortable. Wears well for summer dress attire for taking your lady out for a dinner or show. Casual yet classy. Not a bad buy.

I wanted to love these
Size: 9, Color: Black Leather
These are very good looking in person, especially the buckles and the pop of red on black. Alas, I have another pair of Marc Joseph shoes to compare comfort and fit, and this pair simply hurts my feet.
