U heeft gezocht op: Proteïne-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-ENZOENZ51023KP050

PROTEOSTAT® protein aggregation assay

Catalogus nummer: (ENZOENZ51023KP050)
Leverancier: ENZO LIFE SCIENCES
Omschrijving: PROTEOSTAT® Protein aggregation assay provides a simple, homogenous assay format for monitoring peptide and protein aggregation in solution. This is useful for defining optimal storage formulations for proteins, for screening of compounds that promote or inhibit protein aggregation and potentially for the sensitive measurement of molecular chaperone activity. The assay can be employed to streamline protein processing and formulation optimization procedures.

Product Image-M172-1L

VWR®, Bradford protein assay, proteomics grade

Catalogus nummer: (M172-1L)
Leverancier: VWR Chemicals
Omschrijving: 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.

Product Image-786-12XT

Protein quantitation assay kits, CB-X™ Protein assay

Leverancier: G-Biosciences
Omschrijving: 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.

Image Unavailable-USBIO8061-100

Osteoclast inhibitory lectin MAB MO XMO

Catalogus nummer: (USBIO8061-100)
Leverancier: US Biological
Omschrijving: 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.

PROTEOSTAT® protein refolding and aggregation sensing kit for microplates

Catalogus nummer: (ENZOENZ51040KP002)
Leverancier: ENZO LIFE SCIENCES
Omschrijving: ProteoStat® Protein refolding and aggregation sensing kit provides a fractional factorial matrix design to facilitate screening of refolding parameters for a specific protein in different buffers, and a simple, homogenous assay format for monitoring protein aggregation using a red-emitting aggregation-sensitive dye. 
UOM: 1 * 1 Kit
Product Image-733-1995

Protein quantitation assay kits, CB™ Protein assay

Leverancier: G-Biosciences
Omschrijving: 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.
