Anti-Rat IgG (H&L) (ATTO 550 Conjugated) Pre-Adsorbed Secondary Antibody

Polyclonal

ATTO ® dyes can be used for multicolor immunofluorescent detection with low background and high signal. Examples shown are:
A. Tubulin in PtK2- male Rat Kangaroo Kidney Epithelial Cells was detected using ATTO 532 labeled secondary antibody.
B. Muscle alpha-actin was stained with a mouse primary antibody and ATTO 488 anti-mouse IgG (green) while Cytokeratin was stained with polyclonal rabbit anti-cytokeratin and ATTO 647N anti-rabbit IgG (red).
C. HUVEC (Human umbilical vein endothelial cells were stained with anti- Vimentin-ATTO 532 (green), anti-E-Cadherin-ATTO 655 (red) and DAPI (blue).
D. Rat colon sections were stained with Anti-Aquaporin 3-ATTO 594 antibody. Hoechst 33342 (blue) is used as counterstain.

Atto™ dyes can be used for multicolor immunofluorescent detection with low background and high signal. Example shown here is Immunohistochemical staining using ATTO-550 Anti-Aquaporin 2-antibody (red) of paraffin embedded region of rat kidney showing a transversal cut of the inner medulla near to the renal papilla. Nuclei are visualized with Hoechst 33342 (blue). Images provided courtesy of Dr. Jörg Reichwein, ATTO-TEC GmbH

Rat IgG (H&L) Antibody ATTO 550 was prepared from monospecific antiserum by immunoaffinity chromatography using Rat IgG coupled to agarose beads followed by solid phase adsorption(s) to remove any unwanted reactivities.  Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Goat Serum, Rat IgG and Rat Serum.  No reaction was observed against Bovine, Chicken, Goat, Guinea Pig, Hamster, Horse, Human, Mouse, Rabbit and Sheep Serum Proteins.  This antibody will react with heavy chains of rat IgG and with light chains of most rat immunoglobulins.
