The Quant-iT Protein Assay Kit makes protein quantitation easy and accurate. The kit provides concentrated assay reagent, dilution buffer, and pre-diluted BSA standards. Simply dilute the reagent, load it into the wells of a microplate, add 1-20 μL of sample, mix, then measure the fluorescence. The assay is highly selective for protein and exhibits very little protein-to-protein variation. The assay is performed at room temperature, and the signal is stable for 3 hours. Common contaminants, such as salts, solvents, or DNA—but not detergents—are well tolerated in the assay. Quant-iT DNA Assay Kits (Q33120, Q33130) and a Quant-iT RNA Assay Kit (Q33140) are also available.

常见问题解答 (FAQ)

为什么我用Qubit Assay检测时会得到负的荧光值?

负的荧光值物理上是不可能的。它是由于软件自动扣除背景信号而造成的假象。这意味着你的荧光计检测到背景信号并将其扣除从而牺牲了真实数据。务必做一个仅有缓冲液的对照并评估信号的类型。你可能需要换用另外一块板。

我有一个Quant-iT DNA试剂盒,而想在Qubit荧光计上使用。可以吗?

是的,使用手册中有关于此项应用的说明。你将使用0 ng/μL lambda dsDNA HS标准品制备Standard #1。你将稀释一个10 ng/μL lambda dsDNA HS标准品得到Standard #2。然后你准备样本并将它们和上述的两点标准曲线进行比较。Quant-iT dsDNA BR试剂盒也可以用类似的方式使用。

这些Quant-iT试剂盒的适用pH范围是多少?

试剂盒中的缓冲液将保证合适的pH值范围,即使您的DNA处于这一pH范围之外也没关系,因为检测中所用的缓冲液体积至少超过样本体积的10倍。

我试图对一些带有荧光基团标记的DNA进行定量。这可行吗?

PicoGreen染料和其它基于荧光定量的试剂不建议用于对染料偶联的核酸进行定量。核酸上携带的染料基团会干扰定量试剂的结合或荧光产生。

DNA长度对dsDNA检测结果有影响吗?

大致在20-mer或更短范围内的链信号水平较低。对于大部分由短链组成的dsDNA样本,仍可使用试剂,但应使用与样本长度相当的dsDNA标准品。

Abstract
Acrolein inhibits cytokine gene expression by alkylating cysteine and arginine residues in the NF-kappaB1 DNA binding domain.
Authors:Lambert C, Li J, Jonscher K, Yang TC, Reigan P, Quintana M, Harvey J, Freed BM,
Journal:J Biol Chem
PubMed ID:17491020
Cigarette smoke is a potent inhibitor of pulmonary T cell responses, resulting in decreased immune surveillance and an increased incidence of respiratory tract infections. The alpha,beta-unsaturated aldehydes in cigarette smoke (acrolein and crotonaldehyde) inhibited production of interleukin-2 (IL-2), IL-10, granulocyte-macrophage colony-stimulating factor, interferon-gamma, and tumor necrosis factor-alpha by human T ... More
Functional selection of phagocytosis-promoting genes: cell sorting-based selection.

Phagocytosis is a critical host defense mechanism that clears invading pathogens, apoptotic cells, and cell debris; it is an essential process for normal development, tissue remodeling, immune response, and inflammation. Here, a functional selection strategy was used to isolate novel phagocytosis-promoting genes. After the retroviral transfer of mouse brain cDNA ... More

Dye-based protein determination assays are widely used to estimate protein concentration, however various reports suggest that the response is dependent on the composition and sequence of the protein, limiting confidence in the resulting concentration estimates. In this study a diverse set of model proteins representing various sizes of protein and ... More
Targeted quantitation of overexpressed and endogenous cystic fibrosis transmembrane conductance regulator using multiple reaction monitoring tandem mass spectrometry and oxygen stable isotope dilution.
Authors:Jiang H, Ramos AA, Yao X,
Journal:Anal Chem
PubMed ID:19947594
Cystic fibrosis transmembrane conductance regulator (CFTR) functions as an ion channel in the apical plasma membrane of epithelial cells. Mutations in the gene coding for CFTR cause cystic fibrosis (CF). A major cellular dysfunction is insufficient apical plasma membrane expression of the protein. Its correction is important for developing new ... More
