Donkey Anti-Guinea Pig IgG (H+L) ATTO488
Antibody produced in donkey, affinity purified
Cat. #: 3203-1MG
Applications
Suited for fluorescence-based methods including immunofluorescence microscopy; preservative- and protein-additive-free (e.g., no BSA), supporting sensitive workflows and live-cell techniques.
Description
| Product name | Donkey Anti-Guinea Pig IgG (H+L) ATTO488 | DXGP488 |
| Target species | Guinea Pig |
| Description |
ATTO-labeled secondary antibodies are a new generation of fluorescent reagents characterized by high fluorescence intensity and strong photostability. Donkey Anti-Guinea Pig IgG (H+L) ATTO488 is antigen-specific; affinity purification effectively removes donkey serum proteins, including immunoglobulins not specifically binding to guinea pig IgG. The antibody is conjugated to ATTO488 (λex 501 nm | λem 523 nm) and subsequently purified by size-exclusion chromatography (SEC). Anti-Guinea Pig IgG ATTO488 is particularly suited for high-resolution microscopy due to its high photostability and strong fluorescence quantum yield. This reagent is free of preservatives and protein additives (such as BSA), supporting sensitive fluorescence applications including live-cell techniques. It is supplied as a lyophilized powder (1.0 mg) and shipped at room temperature; a glycerol buffer is provided for convenient reconstitution and subsequent storage at -20°C (including aliquoting for repeated use). |
| Specification | Immunofluorescence: 1:500–1:1500, Degree of labeling (DOL): 2–9, Unconjugated dye ≤5% of total fluorescence. |
| Optical Properties | λex: 501 nm, λem: 523 nm |
Properties
