You Searched For: Protein Assays

Accurately quantifying total protein concentration is a key to most experiments and is often necessary for isolation, separation, and analysis of proteins by biochemical methods. When it is necessary to determine the total protein concentration in a sample, one of the first factors to consider is the selection of a protein assay method. These choices are typically based upon the compatibility of the method with the samples to be assayed. Each method has its own advantages and disadvantages.

Product Image-M172-1L

VWR®, Bradford protein assay, proteomics grade

Catalog Number: (M172-1L)
Supplier: VWR Chemicals
Description: The Bradford protein assay is the preferred colorimetric assay for quantifying total protein concentration. Based upon complex formation between basic and aromatic amino acid residues with Coomassie® Brilliant Blue G-250 dye, the Bradford method is easier, faster, and more sensitive than the Lowry method.

Osteoclast inhibitory lectin MAB MO XMO

Catalog Number: (USBIO8061-100)
Supplier: US Biological
Description: Osteocrin is a recently identified secreted protein expression of which was only detected in bone, peaking just after birth and decreasing markedly with age. A 1280-bp mRNA encodes osteocrin producing a mature protein of 103 amino acids with a molecular mass of 11,4 kD. In primary osteoblastic cell cultures osteocrin expression coincided with matrix formation then decreased in very mature cultures.

Protein quantitation assay kits, CB™ Protein assay

Supplier: G-Biosciences
Description: CB™ Protein Assay, a Coomassie dye based protein assay based on the Bradford Protein Assay, is suitable for the simple and rapid estimation of protein concentration. The binding of protein to the dye results in a colour change from brown to blue. The change in colour density is proportional to protein concentration. Protein estimation can be performed using as little as 0,5 µg protein.

Product Image-786-12X

Protein quantitation assay kits, CB-X™ Protein assay

Supplier: G-Biosciences
Description: CB-X™ Protein Assay is a Coomassie dye based protein assay based on the Bradford Protein Assay. For protein samples in simple, uncomplicated aqueous buffers CB-X™ is a highly sensitive, single reagent assay that can be performed in 5 minutes. For complicated protein samples, CB-X™ Protein Assay is supplied with reagents to clean up the samples and remove all reagents and chemicals that interfere with accurate protein estimation in a single step. These reagents include detergents, chaotropes, reducing agents, alkylating agents, sugars, high salt concentrations, buffering agents and chelating agents. The clean up stage and subsequent protein assay is performed in a single tube to ensure no protein loss and to maintain the accuracy of the assay.

Antibody labelling kits, HisTag® Antibody HRP Conjugate kit

Catalog Number: (71840-3)
Supplier: Merck Millipore (Novagen)
Description: The HisTag® Antibody HRP Conjugate kit contains a horseradish peroxidase-conjugated HisTag® Monoclonal Antibody that is useful as a single detection reagent, thus eliminating cross-reactivity associated with secondary antibody reagents. It recognises five consecutive histidine residues regardless of the surrounding amino acid context. The purified antibody conjugate produces a strong signal at a 1:1000 to 1:2000 dilution on Western blots and dot blots. The HisTag® Antibody HRP Conjugate also detects the recombinant marker bands in the Novagen Perfect Protein™ Western Markers for convenient visualisation of accurate internal standards on Western blots.
