FITC is not membrane permeable in healthy cells, it binds to surface proteins. Conjugates such as FITC-Dextran is an example of a more cell-permeable option.

General description
また、アミン基を介してタンパク質に蛍光標識を付けるために広く使用されています。イソチオシアネート基は、タンパク質のアミノ末端および第一級アミンと反応します。抗体やレクチンなどタンパク質の標識に使用されています。
フルオレセインイソチオシアネート異性体Iは、接触感作物質として提案されています。
Application
生物学的用途には、タンパク質の蛍光標識試薬、タンパク質追跡用の蛍光試薬、および病原体を迅速に同定するための蛍光抗体法の試薬としての使用などがあります。これは、それらのキャピラリー電気泳動(CE)測定時に、ヒト尿中のアンフェタミン、メタンフェタミン、3,4-メチレンジオキシメタンフェタミンおよびP-フェニルエチルアミンの誘導体化試薬として使用される場合があります。これは、蛍光抗体の調製に使用される場合があります。また、in vitro感作試験に使用されました。

Is the intensity of FITC (e.g., Product No. F7250) pH dependent?
1 回答-
Yes; many articles have reported the pH dependence of the fluorescence of fluorescein derivatives. See the following references: Archives Biochem. Biophys., 133, 263 (1969); J. Immunol., 95, 1165 (1966); Archives Biochem. Biophys., 73, 1 (1958); Standard test for labeling efficiency of FITC with BSA: NCCLS Approved Standard: ASM-1, 2nd ed., June, 1975; Characterization of FITC-dyes by IR and TLC: Analytical Biochem., 29, 526 (1969); Fluorescent labeling of proteins: Proc. Nat. Acad. Sci., 72, 459 (1975); Amer. J. Pathol., 34, 1081 (1958); Fluorescent labeling of a lectin: Meth. Enzymol., 81, 65 (1982).

After the FITC (e.g., Product No. F7250) is conjugated to the protein, what is the solution stability of the conjugated protein?
1 回答-
The stability of the conjugated protein will be essentially the stability of the unconjugated protein. Some conjugated proteins might be stable when stored at -20°C and other conjugated proteins will have better solution stability at 2-8°C If the protein concentration is too low, this also has a negative effect upon the stability of the conjugated protein.

How stable is FITC Isomer 1 (e.g., Product No. F7250) once conjugated to an antibody?
1 回答-
FITC can photo bleach fairly rapidly. The prepared solution should be stored in a dark container and protected from light. When viewing the antibody staining under a microscope, it is advisable to use subdued fluorescent light when possible. If the fluorescent light stays at one position for too long, photo bleaching is noticeable.
