Most mammalian cells transport glucose through a family of membrane proteins known as glucose transporters.
Molecular cloning of these glucose transporters has identified a family of closely related genes that encodes at least 7 proteins (Glut-1 to Glut-7, MW.
40-60kD) and Sodium glucose co-transporter-1 (SGLT-1, 662 amino acids; ~75kD).
Individual member of this family have identical predicted secondary structures with 12 transmembrane domains.
Both N and c-termini are predicted to be cytoplasmic.
Most differences in sequence homology exist within the four hydrophilic domains that may play a role in tissue-specific targeting.
Glut isoforms differ in their tissue expression, substrate specificity and kinetic characteristics.
Glut-1 mediates glucose transport into red cells, and throughout the blood brain barrier, and supply glucose to most cells.
Glut-2 provides glucose to the liver and pancreatic cells.
Glut-3 is the main transporter in neurons, whereas Glut-4 is primarily expressed in muscle and adipose tissue and regulated by insulin.
Glut-5 transports fructose in intestine and testis.
Glut-6 is a pseudoegene and unlikely to be expressed at the protein level.
Glut-7, expressed in liver and other gluconeogenic tissues, mediates glucose flux across endoplasmic reticulum membrane.
Glut-8 is found in adult testis and placenta.
Human Glut-9 is expressed in spleen, peripheral leukocytes and brain.
Human Glut-10 (541 aa, chromosome 20q13.1; ~30-35% homology with Glut-3 and Glut-8) has been identified as a candidate gene for NIDDM susceptibility.
It is widely expressed with highest levels in liver and pancreas.
Glut-11 (496 aa, chromosome 22q11.2; ~41% identity with Glut-5) is expressed in heart and skeletal muscle.
Applications:Suitable for use in ELISA, Western Blotting.
Other applications not tested.
Recommended Dilution:Western Blot: 1:1000-1:5000 for antiserum and 1-10ug/ml for affinity pure IgG using ECL.
ELISA: 1:10,000-50,000 for neat serum and 0.5-1ug/ml for affinity pure.
Control peptide can be used to coat ELISA plates at 1ug/ml.
Optimal dilutions to be determined by the researcher.
Storage and Stability:May be stored at 4°C for short-term only.
For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%).
Freeze at -20°C.
Aliquots are stable for at least 12 months at -20°C.
For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Further dilutions can be made in assay buffer.
仕様
Size:100ug
Host:rabbit
Source Antibody:mouse
Grade:Affinity Purified
Purity:Purified by immunoaffinity chromatography.
Form:Supplied as a liquid in PBS, pH 7.4 and 0.09% sodium azide, 40% glycerol.
Specificity:Mouse peptide sequence is 90% conserved in rat and human Glut-8. No significant sequence homology is seen with other transporters. Antibody crossreactivity in various species is not established. Control peptide, because of its low MW (<3kD), is not suitable for Western. It should be used in ELISA or antibody blocking experiments (use 5-10 ug of control peptide per 1 ug IgG or 1 ul of antiserum) to confirm antibody specificity.
Isotype:IgG
Calc Applications Abbrev:E WB
Calc Crossreactivity:Mo
Immunogen:An 11-AA peptide sequence near the C-terminus of mouse Glut-8 (1). A cysteine has been added at the NH2 terminus for coupling to KLH.
