Clone 26/LEDGF

(RUO)

Western blot analysis of LEDGF on a HeLa cell lysate (Human cervical epitheloid carcinoma; ATCC CCL-2.2) (left). Lane 1: 1:1000, lane 2: 1:2000, lane 3: 1:4000 dilution of the mouse anti-human LEDGF antibody. Immunofluorescent staining of SK-N-SH cells (Human neuroblastoma; ATCC HTB-11) (right). Cells were seeded in collagen coated 384-well imaging microplates (Material # 353962) at ~ 8,000 cells per well. After overnight incubation, cells were stained using the Triton-X 100 fix/perm protocol (see Recommended Assay Procedure) and the mouse anti-human LEDGF antibody. The second step reagent was Alexa Fluor® 488 goat anti mouse Ig (Invitrogen) (pseudo-colored green) and counter-stained with Hoechst 33342 (pseudo-colored blue). The images were captured on a BD Pathway™ 855 or 435 Bioimager system using a 20x objective and merged using BD Attovision™ software. This antibody also stained SH-SY5Y (Human neuroblastoma; ATCC CRL-2266), C6 (Rat glioma; ATCC CCL-107), U-87 MG (Human glioblastoma cells; ATCC HTB-14) and U-373 cells (Human glioblastoma cells; ATCC HTB-17; discontinued, investigators may refer to: http://www.atcc.org/MisidentifiedCellLines/tabid/683/Default.aspx ) using both the Triton-X 100 and methanol fix/perm protocols (see Recommended Assay Procedure).

Methanol Procedure for a 96 well plate:

Remove media from wells. Add 100 µl/well fresh 3.7% Formaldehyde in PBS. Incubate for 10 minutes at room temperature (RT). Flick out and add 100 µl/well 90% methanol. Incubate for 5 minutes at RT. Flick out and wash twice with PBS. Flick out PBS and add 100 µl/well blocking buffer (3% FBS in PBS). Incubate for 30 minutes at RT. Flick out and add diluted antibody (diluted in blocking buffer). Incubate for 1 hour at RT. Wash three times with PBS. Flick out PBS and add second step reagent. Incubate for 1 hour at RT. Wash three times with PBS. Image sample.

Triton-X 100 Procedure for a 96 well plate:

Remove media from wells. Add 100 µl/well fresh 3.7% Formaldehyde in PBS. Incubate for 10 minutes at room temperature (RT). Flick out and add 100 µl/well 0.1% Triton-X 100. Incubate for 5 minutes at RT. Flick out and wash twice with PBS. Flick out PBS and add 100 µl/well blocking buffer (3% FBS in PBS). Incubate for 30 minutes at RT. Flick out and add diluted antibody (diluted in blocking buffer). Incubate for 1 hour at RT. Flick out and wash three times with PBS. Flick out and add second step reagent. Incubate for 1 hour at RT. Flick out and wash three times with PBS. Image sample.

Product Notices

Since applications vary, each investigator should titrate the reagent to obtain optimal results.

Antibody Details

26/LEDGF

p52/p75 proteins were first identified through their interaction with transcriptional factors and splicing factors. p75 is encoded by exons 1-15 and contains 530 amino acids, while the alternatively spliced p52 is encoded by exons 1-9 and contains 333 amino acids. Both p52 and p75 have strong interactions with the VP16 activation domain and with various components of the general transcriptional machinery. p52 is the more active transcription activator and has also been shown to recruit the pre-mRNA splicing factor ASF/SF to sites of active transcription. Interestingly, p52/p75 has also been identified as Lens Epithelium-Derived Growth Factor (LEDGF). In serum free media, LEDGF stimulates the growth and survival of a variety of cells, such as lens epithelial cells, retinal photoreceptor cells, COS7 cells, skin fibroblasts, and keratinocytes. In retinal photoreceptor cells, LEDGF is found in the nucleus where it promotes resistance to serum starvation and thermal stress. Thus, the LEDGF gene encodes splice variants that may regulate gene transcription and mRNA splicing of a variety of proteins that are essential for cell growth and survival.

Format Details

Purified

Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.

Format: Purified
