Recombinant Blue Fluorescent Protein antibody (Alexa Fluor 647)

Catalog No. ABIN6953240

Product Details anti-Blue Fluorescent Protein Antibody (Alexa Fluor 647)

Target: Blue Fluorescent Protein (BFP)

Antibody Type: Recombinant Antibody

Fragment: single-domain Antibody (sdAb)

Reactivity: Entacmaea quadricolor

Host: Alpaca

Expression System: E.coli

Clonality: Monoclonal

Conjugate: This Blue Fluorescent Protein antibody is conjugated to Alexa Fluor 647

Application: Flow Cytometry (FACS), Immunocytochemistry (ICC), Immunofluorescence (IF)

Purpose: Camelid sdAb anti-TagBFP conjugated with Alexa647, Clone 1H7

Specificity: Recognizes mTagBFP, mKate, mKate2, mTagRFP, mTagRFP657 and most common fluorescent proteins deriving from Entacmaea quadricolor

Cross-Reactivity (Details): Does not cross-react with common GFP- or dsRed derivatives.

Characteristics: A dye conjugated alpaca single-domain antibody (sdAb), also referred to as VHH or nanobody. It is in the range of 15 kDa and 3 nm in molecular weight and size respectively. This means that sdAbs are ten times lighter and up to 5x smaller than a conventional IgG molecule. They can position a fluorophore up to 20 nm closer to the intended target than using conventional primary-secondary antibody complex detection.

Purification: The antibody produced in E.coli is derived from a single-domain antibody (sdAb) that recognizes fluorescent proteins deriving from Entacmaea quadricolor, such as mTagBFP, mTagRFP, mTagRFP657, and mKate with high affinity and specificity.

Clone: 1H7

Labeling Ratio: a single fluorophore is coupled to exactly one sdAb

Application Details

Application Notes: Recommended dilution 1:500

Comment:

Each fluorophore is coupled to exactly one sdAb, which in turn binds to its target molecule in a monovalent fashion. The high binding affinity and a high coupling efficiency of > 95% guarantees a highly linear relation between target molecule number and fluorescent intensity. This enables you to directly count your target molecule of interest. The fluorophore is located exceptionally close to the recognized epitope (< 1.5 nm), which is ideal for all microscopy techniques.
