Depositors Notes: This antibody appears to be Xenopus-specific and doesn't cross react with mouse. It recognizes the 55 and 57 kDa vimentin proteins encoded by the genes vim1 and vim4, respectively. 14h7 disrupts vimentin organization when injected into Xenopus A6 cells. 14H7 undergoes frequent class switching from IgG1 to IgG2a.
Gene: vim1 & vim4
Immunogen: Cell insoluble residues derived from the Xenopus kidney epithelial cell line A6 (mainly containing intermediate filaments)
Additional Information: While this antibody has been reported to be Xenopus-specific, Arciniegas et al. [PMID: 10603448] and Gomes et al. [PMID: 22075471] have reported using it succesfully on chicken embryos and mouse cultured ectoplacental cones, respectively.
Positive Tested Species Reactivity: Xenopus
Recommended Applications: Function Blocking, Immunofluorescence, Immunohistochemistry, Western Blot

Storage and Handling Recommendations
Although many cell products are maintained at 4°C for years without loss of activity, shelf-life at 4°C is highly variable.
To ensure retention of antibody activity, we recommend aliquotting the product into two parts:
1) a volume of antibody stored at 4°C to be used within two weeks.
2) the remaining product diluted with an equal volume of molecular grade glycerol and stored at -20°C.
While optimal Ig concentration for an application will vary, a good starting concentration for immunohistochemistry (IHC),
immunofluorescence(IF) and staining is 2-5 µg/ml.
For Western blots, the concentration is decreased by one order of magnitude (that is, 0.2-0.5 µg/ml).
All cell products contain the antimicrobial ProClin. See our FAQ section for additional information.
