Western blot - Anti-Lin28B antibody [EPR25252-20] (AB289978)

Blocking and diluting buffer and concentration : ½ volume of Odyssey Blocking Buffer (TBS)+ ½ volume of 0.1% TBS.

False colour image of Western blot : Anti-Lin28B antibody EPR25252-20 staining at 1/1000 dilution, shown in green; Mouse anti-Tubulin antibody [DM1A] (ab7291) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab289978 was shown to bind specifically to Lin28B. The band was observed at 32 kDa in wild-type HEK293T cell lysates with no signal observed at this size in Lin28B knockout cell line ab265066 (knockout cell lysate ab257504) used. To generate this image, wild-type and Lin28B knockout HEK293T cell lysates were analyzed. First, samples were run on an SDS-PAGE gel then transferred onto an immobilon-FL PVDF membrane. Membranes were blocked in Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed (ab216776) at 1/10000 dilution.

Target data

Suppressor of microRNA (miRNA) biogenesis, including that of let-7 and possibly of miR107, miR-143 and miR-200c. Binds primary let-7 transcripts (pri-let-7), including pri-let-7g and pri-let-7a-1, and sequester them in the nucleolus, away from the microprocessor complex, hence preventing their processing into mature miRNA (PubMed : 22118463). Does not act on pri-miR21 (PubMed : 22118463). The repression of let-7 expression is required for normal development and contributes to maintain the pluripotent state of embryonic stem cells by preventing let-7-mediated differentiation. When overexpressed, recruits ZCCHC11/TUT4 uridylyltransferase to pre-let-7 transcripts, leading to their terminal uridylation and degradation (PubMed : 19703396). This activity might not be relevant in vivo, as LIN28B-mediated inhibition of let-7 miRNA maturation appears to be ZCCHC11-independent (PubMed : 22118463). Interaction with target pre-miRNAs occurs via an 5'-GGAG-3' motif in the pre-miRNA terminal loop. Mediates MYC-induced let-7 repression (By similarity). When overexpressed, isoform 1 stimulates growth of the breast adenocarcinoma cell line MCF-7. Isoform 2 has no effect on cell growth.
