- Isotype: IgG
Product nameAnti-Survivin DEx3 antibody
DescriptionRabbit polyclonal to Survivin DEx3
SpecificityThis antibody has been tested in Western blotting against equal loadings of purified wild type survivin, 2B and DEx3. When used at 1/250, it detects a single clean (but weak) band of the appropriate size for DEx3, but no band is detected with wild type survivin or 2B. We have not succeeded in detecting endogenous Survivin DEx3 using this antibody (Survivin DEx3 is expressed at very low levels). This antibody has been used successfully however, to detect overexpressed Survivin DEx3 in whole cell extracts.

General notesThis antibody should be aliquoted to reduce freeze-thaw cycles as it loses performance quickly after multiple freeze-thaws.

RelevanceSurvivin is expressed in G2/M phase in a cycle regulated manner. At the beginning of mitosis, survivin associates with mitotic spindle microtubules, this is essential for survivin's anti-apoptosis function. Survivin may counteract a default induction of apoptosis in G2 / M phase. Survivin over-expression in cancer may overcome this apoptotic checkpoint. Survivin DEx3 (lacking exon 3) and survivin-2B (retaining a part of intron 2 as a cryptic exon) are isoforms of survivin that behave differently to survivin. Skipping of exon 3 in survivin-Ex3 results in a modification of the BIR domain, followed by an additional frame shift in exon 4. In consequence, the open reading frame of Survivin DEx3 ends in the 3' untranslated region of survivin at position 581 and generates a novel 63 amino acids-long COOH-terminal tail in survivin-Ex3 coded by 87 nucleotides of exon 4 and 103 nucleotides of the original 3' untranslated region. See Mahotka et al. 1999 for more details.

ICC/IF image of ab3731 stained HeLa cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab3731, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
