DESCRIPTION

SLC16A7, also named MCT2, is a proton-coupled monocarboxylate transporter. MCT2/SLC16A7 has the highest affinity for pyruvate and lactate among all the functionally characterized MCTs, serving as a primary pyruvate transporter in humans. In human cancers, MCT2 has been described as strongly expressed in the cytoplasm of colorectal cancer cells, indicating a possible role in intracellular organelles, such as mitochondria.

PRINCIPLE OF THE ASSAY

Sandwich ELISA structure (Detection antibody labeled with HRP) A capture antibody is pre-coated onto the bottom of wells which binds to analyte of interest. A detection antibody labeled with HRP also binds to the analyte. TMB acts as the HRP substrate and the solution color will change from colorless to blue. A stop solution containing sulfuric acid turns solution yellow. The color intensity is proportional to the quantity of bound protein which is measurable at 450 nm with the correction wavelength set at 630 nm.

PRECISION

Intra-assay Precision (Precision within an assay) Three samples of known concentration were tested 8 times on one plate to assess intra-assay precision. Inter-assay Precision (Precision between assays) Three samples of known concentration were tested in 16 separate assays to assess inter-assay precision.

Intra-assay Precision

Sample	n	Mean (pg/mL)	SD	CV%
1	8	1,210.1	41.0	3.4
2	8	400.4	2.4	0.6
3	8	158.2	2.4	1.5

Inter-assay Precision

Sample	n	Mean (pg/mL)	SD	CV%
1	16	1,209.7	30.5	2.5
2	16	397.0	5.4	1.4
3	16	157.5	2.6	1.7

RECOVERY

The recovery of human MCT2/SLC16A7 spiked to three different levels throughout the range of the assay in cell lysate was evaluated.

Sample Type		Average% of Expected	Range (%)
Cell lysate	1:640	107	104-110

LINEARITY

To assess the linearity of the assay, samples were diluted with the appropriate Sample Diluent to produce samples with values within the dynamic range of the assay. (The cell lysate was initially diluted 1:80.)

		Cell lysate
1:2	Average% of Expected	100
	Range (%)	-
1:4	Average% of Expected	98
	Range (%)	92-103
1:8	Average% of Expected	88
	Range (%)	85-91
1:16	Average% of Expected	83
	Range (%)	73-93
