  • Function

    Sodium-independent, high-affinity transport of large neutral amino acids such as phenylalanine, tyrosine, leucine, arginine and tryptophan, when associated with SLC3A2/4F2hc. Involved in cellular amino acid uptake. Acts as an amino acid exchanger. Involved in the transport of L-DOPA across the blood-brain barrier, and that of thyroid hormones triiodothyronine (T3) and thyroxine (T4) across the cell membrane in tissues such as placenta. Plays a role in neuronal cell proliferation (neurogenesis) in brain. Involved in the uptake of methylmercury (MeHg) when administered as the L-cysteine or D,L-homocysteine complexes, and hence plays a role in metal ion homeostasis and toxicity. Involved in the cellular activity of small molecular weight nitrosothiols, via the stereoselective transport of L-nitrosocysteine (L-CNSO) across the transmembrane. May play an important role in high-grade gliomas. Mediates blood-to-retina L-leucine transport across the inner blood-retinal barrier which in turn may play a key role in maintaining large neutral amino acids as well as neurotransmitters in the neural retina. Acts as the major transporter of tyrosine in fibroblasts.
  • Tissue specificity

    Expressed abundantly in adult lung, liver, brain, skeletal muscle, placenta, bone marrow, testis, resting lymphocytes and monocytes, and in fetal liver. Weaker expression in thymus, cornea, retina, peripheral leukocytes, spleen, kidney, colon and lymph node. During gestation, expression in the placenta was significantly stronger at full-term than at the mid-trimester stage. Also expressed in all human tumor cell lines tested and in the astrocytic process of primary astrocytic gliomas. Expressed in retinal endothelial cells and in the intestinal epithelial cell line Caco-2.
  • Sequence similarities

    Belongs to the amino acid-polyamine-organocation (APC) superfamily. L-type amino acid transporter (LAT) (TC 2.A.3.8) family.
  • Cellular localization

    Cytoplasm > cytosol. Apical cell membrane. Located to the plasma membrane by SLC3A2/4F2hc. Localized to the apical membrane of placental syncytiophoblastic cells. Expressed in both luminal and abluminal membranes of brain capillary endothelial cells.

  • ICC/IF image of ab85226 stained MCF7 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab85226, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for contacting us.

Yes, both ab85226 and ab134121 detect the same SLC7A5 (LAT1) protein. http://www.uniprot.org/uniprot/Q01650

We would guarantee ab134121 to work in WB, IP, and IHC-P with human samples. We know that it does not work well with Flow Cyt, ICC/IF and rat or mouse samples.

Cat # ab89545 is an EEA1 antibody no longer available on our catalogue. You must mean ab29545, the HeLa cell lysate. Yes, that would be a good positive control for use with ab134121.

In WB with ab134141, we recommend a working dilution of 1/1000 - 1/10000. The amount that you will need will depend on the amount present in your samples. The image generated on our website was done with a 1/1000 dilution for example.

A suitable secondary would be Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (HRP) to be used with ECL detection, like our ab133406.

Thanks for your inquiry. From all the information available, there is no preferred antigen retrieval step for ab85226. I have attached the standard antigen retrieval step for IHC as part of the IHC-P protocol. Please refer to the antigen retrieval part. I hope this was helpful. Please feel free to contact me if you require further assistance.
