Background Information
MCT1, the SLC16A1 gene product, is a trans-membrane symporter involved in lactate and pyruvate transportation. It plays an important role in lactic acid transport and H+ clearance in cancer cells. MCT overexpression had been observed in various cancers and may play an important role in tumorigenesis. Two isoforms of MCT1 exist due to the alternative splicing, with predicted MW of 54 kDa and 46 kDa, respectively. While western blot analysis detected MCT1 at an apparent molecular mass of 40-50 kDa.

Reviews
What customers say
Across 8 reviews, this MCT4 antibody receives predominantly 5-star ratings. Users report clear, specific bands at the expected ~40 kDa in Western blot across diverse samples including A549, Ishikawa cells, head and neck cancer lines, and iPSC-derived microglia. Immunofluorescence in brain tissue and other samples yielded strong positive staining. One user confirmed functional validation by observing reduced MCT4 signal upon inhibitor treatment. Recommended dilutions range from 1:200 (IF) to 1:10,000 (WB). Overall, reviewers highlight reliable performance across WB, IF, and IP applications with good specificity.

Angie (Verified Customer) (08-27-2024) | A549 lysate was subjected to western blot with MCT1 antibody used at 1:10000 dilution and incubated at room temperature for 1.5 hours. Secondary antibody Donkey-anti-rabbit (Alexa Fluor 800) used at 1:20000 dilution incubated at room temperature for 1 hour. One thick band at around 40 kDa. Image is shown in grayscale.

Xie (Verified Customer) (07-07-2023) | The expression of MCT4 was seen in my samples.
 |
Aderonke (Verified Customer) (05-23-2023) | The expression of MCT4 was seen in three of the five cell lines used without an inhibitor. Also, an inhibtor of MCT4, was used at two different concentrations and the expression was decreased in the cells that expressed the protein.
