General description【一般描述】 | Beta Amyloid (1-42), ultra pure, HCl MOL. WT.: 4514.3 Da by Mass Spec Analysis (theoretical 4514.10) SEQUENCE: H-Asp-Ala-Glu-Phe-Arg-His-Asp-Ser-Gly-Tyr-Glu-Val-His-His-Gln-Lys-Leu-Val-Phe-Phe-Ala-Glu-Asp-Val-Gly-Ser-Asn-Lys-Gly-Ala-Ile-Ile-Gly-Leu-Met-Val-Gly-Gly-Val-Val-Ile-Ala-OH PEPTIDE CONTENT: 1 mg per vial; salt content is <10% COUNTER ION: HCl |
Application【应用】 | Research Category Neuroscience Research Sub Category Neurodegenerative Diseases Different researchers claim enhanced activity due to different salts. The TFA salt is what has been the industry standard. The HFIP makes the beta-amyloid homogenously monomeric. The NaOH apparently make it monomeric too and is also water soluble, which the TFA salt and HFIP are not. The HCl salt is supposed to be more biological, as TFA is not found in the body. By offering the different salts, it lets the researchers duplicate the different assays that have been developed by other researchers (see below). TFA: Shu-chuan Jao, S-C, et. al. 1997, Amyloid; Int J Exp. Clinical Invest. 4, 231 HFIP: Stine, W.B. et. al. 2003, J. Biol. Chem, 278, 11612 NaOH: Fezoui, Y., et. al. 2000, Amyloid, 7, 166 HCL: Kanek, I and Tutumi, S., 1997, J. Neurochem, 68, 438 |
Physical form【外形】 | White lyophilized powder. Resuspend in any one of the following solvents: 0.1% TFA, 5 mM HCl, 2 mM NaOH, 0.2% NH4OH at a concentration of 1 mg/mL. Sonicate for 30 seconds to 1 minute after it has gone into solution. To bring into your solution: After resuspension, add 5x or 10x buffer stock (PBS, TBS) and water to bring to 1x buffer. |
