Immunofluorescence (IF)
(Fluorescent confocal image of SY5Y cells stained with LIN28B (N-term) antibody. SY5Y cells were fixed with 4% PFA (20 min), permeabilized with Triton X-100 (0.2%, 30 min). Cells were then incubated with MBS9207521 LIN28B (N-term) primary antibody (1:100, 2 h at room temperature). For secondary antibody, Alexa Fluor 488 conjugated donkey anti-rabbit antibody (green) was used (1:1000, 1h). Nuclei were counterstained with Hoechst 33342 (blue) (10 ug/ml, 5 min).

NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene belongs to the lin-28 family, which is characterized by the presence of a cold-shock domain and a pair of CCHC zinc finger domains. This gene is highly expressed in testis, fetal liver, placenta, and in primary human tumors and cancer cell lines. It is negatively regulated by microRNAs that target sites in the 3' UTR, and overexpression of this gene in primary tumors is linked to the repression of let-7 family of microRNAs and derepression of let-7 targets, which facilitates cellular transformation.

Uniprot Description
LIN28B: Acts as a suppressor of microRNA (miRNA) biogenesis by specifically binding the precursor let-7 (pre-let-7), a miRNA precursor. Acts by binding pre-let-7 and recruiting ZCCHC11/TUT4 uridylyltransferase, leading to the terminal uridylation of pre- let-7. Uridylated pre-let-7 miRNAs fail to be processed by Dicer and undergo degradation. Specifically recognizes the 5'-GGAG-3' motif in the terminal loop of pre-let-7. Also recognizes and binds non pre-let-7 pre-miRNAs that contain the 5'-GGAG-3' motif in the terminal loop, leading to their terminal uridylation and subsequent degradation. Mediates MYC-mediated let-7 repression. Isoform 1, when overexpressed, stimulates growth of the breast adenocarcinoma cell line MCF-7. Isoform 2 has no effect on cell growth. Interacts with ZCCHC11/TUT4. Might be negatively regulated by the microRNA let-7b. High expression in testis, fetal liver, placenta and in hepatocellular carcinoma (HCC). Isoform 1 is only detected in moderately and poorly differentiated HCC tissues and placenta. Isoform 2 is detected in fetal liver, non-tumor liver tissues, as well as well-differentiated tumor tissues. Belongs to the lin-28 family. 2 isoforms of the human protein are produced by alternative splicing.

Product Notes
The LIN28B lin28b (Catalog #AAA9207521) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The immunogen sequence is 1-30. The LIN28B Antibody (N-term) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's LIN28B can be used in a range of immunoassay formats including, but not limited to, Immunofluorescence (IF), ELISA (EIA), Western Blot (WB), Immunohistochemistry (IHC), Flow Cytometry (FC/FACS). IF~~1:100 WB~~1:1000. Researchers should empirically determine the suitability of the LIN28B lin28b for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "LIN28B, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
