Anti-Fibrinogen polyclonal antibody [Biotin]

Our previous studies using the mass spectrum analysis provided evidence that fibrinopeptide A (FPA) could be a potential biomarker for schizophrenia diagnosis. We sought further to demonstrate that variants in the fibrinogen alpha chain gene (FGA) coded FPA might confer vulnerability to schizophrenia. 1,145 patients with schizophrenia and 1,016 healthy volunteers from the Han population in Northeast China were recruited. The association of three tag single nucleotide polymorphisms (SNPs) (rs2070011 in the 5' UTR, rs2070016 in intron 4, and rs2070022 in the 3'UTR) in FGA and schizophrenia was examined using a case-control study design. Genotypic distributions of these three SNPs were not found to be significantly different between cases and controls (rs2070011: chi(2) = 1.28, P = 0.528; rs2070016: chi(2) = 4.11, P = 0.128; rs2070022: chi(2) = 1.23, P = 0.541). There were also no significant differences in SNP allelic frequencies between cases and controls (all P > 0.05). Additionally, the frequency of haplotypes consisting of alleles of these three SNPs was not significantly different between cases and healthy control subjects (global chi(2) = 9.27, P = 0.159). Our study did not show a significant association of FGA SNPs with schizophrenia. Future studiesmay need to test more FGA SNPs in a larger sample to identify those SNPs with a minor or moderate effect on schizophrenia.

Fluorinated graphene (F-GNS) was synthesized using commercial graphene (GNS) as starting material and introduced in sodium batteries, which exhibited good rate performance, but large voltage gap between discharge and charge process. Ag nanoparticles were employed in freestanding and binder-free F-GNS electrode (the composite film electrode was labeled as FGA) as catalyst, which were shown to strongly facilitate the decomposition of NaF during charge process in sodium/carbon fluorides (Na/CFx) secondary batteries. During discharge process, the discharge voltage with Ag was about the same as that of Na/F-GNS cell. During charge process, the charge voltage of Na/FGA cell was substantially lower (by 480 mV) than that of Na/F-GNS cell, thus leading to a lower overpotential and a higher electric efficiency. Nanosized amorphous discharge products of NaF formed in Na/FGA cells were ascribed as the key role in reducing the polarization. (C) 2020 Elsevier inc. All rights reserved.
