This LIN28A antibody was raised against a peptide derived from the C-terminal region of human LIN28A.


Purified IgG in PBS with 30% glycerol and 0.035% sodium azide. Sodium azide is highly toxic.

Immunocytochemical analysis of LIN28A staining of mouse embryonic stem cells.
Mouse embryonic stem cells (mESCs) grown on mouse embryonic fibroblast feeder cells (MEFs) were fixed with 4% paraformaldehyde for 10 minutes at room temperature. Cells were then permeabilized and blocked by incubating with Blocking Solution containing 5% serum/0.1% Triton X-100 in D-PBS for 2 hours at room temperature. Cells were then incubated with LIN28A antibody (Catalog No. 61191, red) at 1:200 dilution overnight at 4°C, washed with D-PBS, and incubated for 2 hours at room temperature with goat anti-mouse Cy3 secondary antibody at 1:250 dilution. Nuclei were stained with DAPI (blue). Cells were visualized using a Zeiss fluorescent microscope at 20X magnification. Images show that LIN28A antibody specifically stains mESC colonies and does not stain MEFs. Absence of LIN28A staining in a subset of cells within the colonies suggests differentiation. Scale bars, 100 μm.

LIN28 is an evolutionarily conserved RNA-binding protein that serves as a marker of undifferentiated human embryonic stem cells. LIN28 can facilitate the reprogramming of human somatic cells to induced pluripotent stem cells (iPSCs).

Compatible Secondary Antibodies

Active Motif has developed a variety of high-quality secondary antibodies for most applications, with anti-rabbit and anti-mouse conjugates to a broad line of high-quality fluorescent molecules, as well as horse radish peroxidase (HRP).

Some products may be shipped at room temperature. This will not affect their stability or performance. Upon receipt, unconjugated antibodies may be stored at -20°C for up to 2 years. Fluorophore- & enzyme-conjugated antibodies should be stored at 4°C. Fluorophore-conjugated antibodies should be protected from light. Keep reagents on ice when not in storage; to avoid repeated freeze/thaw cycles, we recommend aliquoting items that will be stored frozen into single-use fractions prior to freezing.
