Immunoblotting: 1:1,000-1:2,000 on denatured protein. Western blot: 1:1000-1:5000. Recognizes a 220-240kDA band on denaturing SDS gels. There is also a 60-64kDa band present in most lysates, the identity of this smaller fragment is unknown but it is not seen in lysates not containing human nestin protein.
WI-38 (ATCC# CCL75) can be used as a positive control. U251 cell line is also positive.
Immunocytochemistry: 1:200 on cells fixed in 4% paraformaldehyde and permeabilized with 0.02% Triton
Immunohistochemistry: paraformaldehyde is the preferred fixative: 1:200 on formalin fixed, paraffin embedded tissue sections. Use triton 0.02% in block only; dilution buffer 0.1% BSA; incubations 1-2 hours RT. Human fetal brain is suggested as a positive control. (CA Messam et al, Develop. Brain Res, 134:87-92, 2002; Gu, et al., Brain Res. 943:174-180, 2002). Filamentous staining in the cytoplasm of cells
Optimal working dilutions must be determined by end user.
