Product Name 

Anti-Engrailed and Invected antibody [4D9]抗體說(shuō)明書(shū)

Product type 

Primary antibodies

Description 

Mouse monoclonal [4D9] to Engrailed and Invected

Immunogen 

C-terminal two-thirds of the invected protein were generated in E. coli with the T7 polymerase expression system.

Reacts with 

Chk, Cyfsh, Dm, Xl, Zfsh

Does not react with 

Ms

Specificity 

This antibody recognizes both the engrailed and invected gene products of Drosophila. The antibody is useful for examining the patterning of segmentation from the cellular blastoderm stage onward. Staining is also seen in a large number of CNS neurons including most of the median neuroblast progeny as well as a small number of PNS neurons.

Epitope 

Epitope has been localized to residues 38-58 of the homeodomain.

Tested applications 

IHC-FoFr

Application notes 
（see key）

Recommended dilutions
IHC-FoFr: 1/200. Fix with 4% paraformaldehyde in PBS for 1 hour.
Not yet tested in other applications.
Optimal dilutions/concentrations should be determined by the end user.
Specific protocols
Recommended IHC protocol with ab12454

Relevance 

In Drosophila, the Engrailed gene plays an important role during development in segmentation, where it is required for the formation of posterior compartments. Expression studies have suggested that Engrailed may also function early in organizing the preblastoderm and later in neurogenesis. Engrailed encodes a homeodomain-containing protein that can function as a transcription factor.
Invected is homologous to Engrailed and the gene lies adjacent to that for Engrailed. The function of Invected is unclear.
