Target

  • Function

    Only known pyridoxal phosphate-dependent enzyme that contains heme. Important regulator of hydrogen sulfide, especially in the brain, utilizing cysteine instead of serine to catalyze the formation of hydrogen sulfide. Hydrogen sulfide is a gastratransmitter with signaling and cytoprotective effects such as acting as a neuromodulator in the brain to protect neurons against hypoxic injury.

  • Tissue specificity

    In the adult strongly expressed in liver and pancreas, some expression in heart and brain, weak expression in lung and kidney. In the fetus, expressed in brain, liver and kidney.

  • Pathway

    Amino-acid biosynthesis; L-cysteine biosynthesis; L-cysteine from L-homocysteine and L-serine: step 1/2.

  • Involvement in disease

    Defects in CBS are the cause of cystathionine beta-synthase deficiency (CBSD) [MIM:236200]. CBSD is an enzymatic deficiency resulting in altered sulfur metabolism and homocystinuria. The clinical features of untreated homocystinuria due to CBS deficiency include myopia, ectopia lentis, mental retardation, skeletal anomalies resembling Marfan syndrome, and thromboembolic events. Light skin and hair can also be present. Biochemical features include increased urinary homocystine and methionine.

Answer

Thank you for taking the time to contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from this antibody. Often it is possible to make suggestions that help resolve problems. We will happily offer technical support and in the event that a product is not functioning in the applications cited on the product data sheet (and the problem has been reported within 120 days of purchase), and if it appears that the antibody is at fault, a replacement/credit note/refund will be offered. -I would really appreciate if you could send us an image from the membrane to help us better understand the problem, but, regarding the description of the problem provided, I would say there might probably have been some kind of degradation of the sample, giving as a result a lower (half of the target MW) band. In that case, I would suggest optimising the sample preparation in order to avoid sample degradation. Please make sure phosphatase inhibitors are also used. -I would recommend loading a higher quantity of sample per lane; maybe 20ug would give better results. -Another suggestion I’d propose is increasing the primary antibody concentration to, for instance, 1/500, to obtain a stronger band at the expected molecular weight. -Running a no primary control would help dismiss any secondary antibody failure. - I would also appreciate if you could also provide details of your order (purchase order number, date of purchase, antibody lot number). I hope this information is helpful, thank you for your cooperation. Should the suggestions not improve the results, please do not hesitate to contact us again.
