Comparison of the characteristics of two hemoglobin variants, Hb D-Iran and Hb E, eluting in the Hb A2 window
BACKGROUND Cation exchange-high performance liquid chromatography (CE-HPLC) is most commonly used to evaluate hemoglobin (Hb) variants, which elute in the Hb A2 window. This study aimed to assess prevalence of an uncommon Hb variant, Hb D-Iran, and compare its red cell parameters and peak characteristics with those of Hb E that commonly elutes in the Hb A2 window. METHODS Generally, we assess...
متن کاملComparative studies of Hb Lepore Boston, Hb A2, and Hb A.
Several functional tests were performed to compare Hb A, Hb A2, and Hb Lepore Boston, which has a delta-beta crossover in the region of residues 87 to 116. Oxygen equilibrium curves determined by an automatic apparatus in 0.1 M potassium phosphate buffer, pH 7.0, at 20 degrees showed that the p50 was 5.8 mm Hg for Hb Lepore Boston, in contrast to 8.1 and 10.3 mm Hg for Hb A2 and Hb A, respectiv...
متن کاملHb in Diabetic Patients with Normal ( Hb A ) and Abnormal ( Hb S and Hb C ) Hemoglobins , as Measured
In a recent study (1 ) of diabetic patients with hemoglobins S and C (Hb S and Hb C), we showed a significant decrease in the proportion of glycosylated Hb, as measured by cation-exchange chromatography. We suggested ( I ) that these low values for glycosylated Hb might be caused by the inability of either Hb S or Hb C to undergo glycosylation or by their failure to be eluted from the column wi...
متن کاملPractical Attacks on HB and HB+ Protocols
HB and HB+ are a shared secret-key authentication protocols designed for low-cost devices such as RFID tags. HB+ was proposed by Juels and Weis at Crypto 2005. The security of the protocols relies on the learning parity with noise (LPN) problem, which was proven to be NP-hard. The best known attack on LPN by Levieil and Fouque [13] requires subexponential number of samples and sub-exponential n...
متن کاملMolecular and haematological characterization of compound Hb E/Hb Pyrgos and Hb E/Hb J-Bangkok in Thai patients.
We describe haematological and DNA characterization of haemoglobinopathies in Thai adolescents caused by compound heterozygosities for Hb E [beta26(B8) Glu-Lys] and two other beta-globin chain variants, Hb Pyrgos [beta83(EF7) Gly-Asp] and Hb J Bangkok [beta56(D7) Gly-Asp]. Hb analysis demonstrated that although these two beta-chain variants have separated elution profiles on liquid chromatograp...
