Detection of Human LIN-28A antibody by Western Blot.

Detection of Human LIN‑28A by Western Blot.

Western blot shows lysates of JAR human choriocarcinoma cell line and NTera-2 human testicular embryonic carcinoma cell line. PVDF membrane was probed with 0.1 µg/mL of Goat Anti-Human LIN-28A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3757) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for LIN-28A at approximately 30 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

LIN‑28A in BG01V Human Stem Cells.

LIN-28A was detected in immersion fixed BG01V human embryonic stem cells using 10 µg/mL Goat Anti-Human LIN-28A Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3757) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counter-stained with DAPI (blue).

Detection of LIN-28A by Western Blot

Expression of LIN28 in mouse testis. Western blot analysis was performed on 20 μg of protein extracts for each sample. beta -actin served as a control. Molecular weight standards were marked in kDa. (A) Western blot analysis of LIN28 in adult mouse tissues. (B) Absence of LIN28 in germ cell-deficient XXY* testes. Testes were collected from adult and post-natal day 10-old mice. V6.5 mouse embryonic stem (ES) cells served as a positive control. LIN28 was absent in fibroblast feeder cells. (C) Developmental expression of LIN28 in postnatal testes. Testes were collected from mice of postnatal day 1 through adulthood.

Detection of LIN-28A by Western Blot

Expression and siRNA knockdown of LIN28 in cultured spermatogonia highly enriched for spermatogonial stem cells (SSCs). (A) Immunostaining of SSCs with anti-LIN28 and anti-PLZF or anti-GFRA1 antibodies. Scale bar, 50 μm. (B) Quantitative PCR measurement of Lin28 mRNA levels (n = 3, mean ± SE) in SSCs after siRNA treatment for 30 hours. (C) Decreased LIN28 protein abundance (43% compared to the control) in SSCs after 30 hours of siRNA treatment. The control SSCs were not treated with Lin28 siRNA. Feeder cells served as a negative control. beta -actin served as a loading control. (D) The number of SSCs (n = 3, mean ± SE) with and without Lin28 siRNA treatment. (E) Quantitative measurement of mature let-7g miRNA levels (n = 3, mean ± SE) in SSCs after siRNA treatment for 30 hours.

Background: LIN-28A

Human LIN-28 (Protein lin-28 homolog A; CSDD1, LIN28 and ZCCHC1)  is a 30 kDa (209 amino acids) cytoplasmic RNA-binding protein with an N-terminal cold shock domain and two C-terminal CCHC zinc finger domains. It is expressed by various undifferentiated embryonic cell types and is also present in adult cardiac and skeletal muscle. Expression of LIN-28 has been shown to be regulated by micro-RNA. Human LIN-28 shares 98% and 97% amino acid sequence homology with rat and mouse LIN-28, respectively.
