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.

Perfect cup.
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
I was really happy with the value of money I pay for this set because I’m able to make the perfect cup of coffee at home and save on going to Starbucks or Dutch Bros. They taste so yummy. It’s easy to use.

Café-Quality Sauces at Home ☕🍫
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4), Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
Absolutely love this Torani Puremade variety pack. Every sauce tastes rich, smooth, and high quality just like what you’d get at a coffee shop. The caramel is perfectly buttery, the white chocolate is creamy (not overly sweet), and both chocolate sauces are deep and indulgent. They blend beautifully into hot and iced drinks, drizzle great over desserts, and the squeeze bottles make them super easy to use with no mess. I also really appreciate that they’re made with no artificial flavors or preservatives. If you’re building a home coffee bar or love elevating desserts, this set is 100% worth it. Would definitely repurchase.

Gourmet drizzle of deliciousness
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
Torani is a great product - very happy we were able to order them through Amazon. They last without being refrigerated (but we go through them fast during parties). The syrups taste like they're from an ice cream shop - we use them for ice cream parties for variety. This set is a great price compared to buying in-store. The syrup is not watery, it's a nice thick syrup that is great for coffee or desserts. The consistency is not as thick as a fudge topping, but thick enough to drizzle, if that makes sense. Will buy again!

A must for my coffee station. Great taste and makes me miss a cafe latte a little less. Love the taste of all four.
