anti-Necdin antibody, rabbit serum (NC243)


SKU: 74-100 Research Area: Applications:



Necdin (neurally differentiated embryonal carcinoma-derived protein) is a 325-amino acid residue protein encoded by a cDNA clone isolated from neurally differentiated mouse embryonal carcinoma cells (ref.1). Necdin is a potent growth suppressor that is expressed predominantly in postmitotic cells such as neurons and muscle cells. Necdin has been implicated in the pathogenesis of Prader-Willi syndrome, a human neurodevelopmental disorder associated with genomic imprinting. Furthermore, necdin binds to major transcription factors E2F1 and p53, and also to NEFA and nucleobindin, both of which are calcium-binding proteins involved in intracellular calcium homeostasis. From these findings necdin is suggested to target various factors involved in the regulation of cell proliferation and survival, and plays a key role in development and differentiation of subsets of neurons in the brain. An antibody (named NC243) against mouse necdin was raised in rabbit (ref.1) in the laboratory of Prof. K. Yoshikawa at Osaka Univ.

Fig.1.Western blotting of Necdin in the crude extract of mouse embryo.

The extract (20 μg protein)) was prepared from cerebral cortex of E 16.5 mouse embryo. The anti-Necdin antibody (NC143) was used at 1/3,000 dilution. Molecular mass of mouse Necdin is 37 kDa. The larger size reported here and elsewhere (see Ref) may reflect post-translational modifications such as ubiquitination and phosphorylation at several sites (Swiss-Prot)


Fig.2 Validation of the anti-necdin antibody with knock-out mice.

Proteins in forebrain lysates from wild-type and necdin knock-out mouse embryos at E14.5 were analyzed by Western blotting. Each lane represents the extract from one littermate. Protein levels were normalized to β-tublin.  (Image from Minamido R et al. PLoS One. 9 (1) PMID: 24392139.)


Fig.3 Immunoprecipitation of necdin

HEK293A cells were transfected with expression vectors for necdin (+). Cell lysates were immunoprecipitated and immunoblotted with anti-necdin antibody. HEK293A cell lysate (-) is a negative control. (Image from Minamido R et al. PLoS One. 9 (1) PMID: 24392139)

Primary NPCs were prepared from the neocortex at E14.5 and subjected to double-immunostaining for necdin and nestin. DNA was stained with Hoechst 33342. Necdin was immunostained with anti-necdin antibody (NC243) and Nestin with anti-nestin antibody (ST1; Cat.# 73-105)  (Images from Minamido R et al. PLoS One. 9 (1) PMID: 24392139.)

Cryosections were prepared from wild-type (WT) and necdin-null (KO) mice at E14.5 and immunostained for necdin. Antibody was used at 1/500 dilution.

E13.5 forebrain cryosections were immunostained for necdin.

CX, Cortex; LV, lateral ventricle; LGE, lateral ganglionic eminence; SP, septum. The antibody was used at 1/500 dilution.
