Бренд:

The sequence of cell cycle events is governed by an array of proteins which regulates the essential process of cell division. The present study involved extraction of proteins from interphase and mitotic CHO cells, their purification and characterization by protein profiling and estimation of protein concentration. Protein profiling by SDS PAGE confirmed the presence of proteins unique to mitotic extracts with particular reference to a protein of molecular weight ~ 38 kDa . The study also focused on generating polyclonal antibodies against CHO cytosolic mitotic extract, testing their reactivity and employing them to mediate mitotic inhibition. Inhibition of mitosis was observed in a dose dependent manner. The results of the evaluation of homogeneity of cytosolic protein antigens tested by a combination of precipitation reactions in extracted protein solutions and also in situ whole cells by immunofluorescence confirmed that the reactivity of the antiserum was restricted to protein antigens of cancerous cell lines(CHO, Vero and HeLa) and that extracts from normal cells(lymphocytes) failed to react with the same.

Induced Mutation on Plants by Laser and other Mutagens

Induced Mutation on Plants by Laser and other Mutagens venkatachalam deepa parvathi and maddaly ravi anti mitotic polyclonal antibodies for mitotic inhibition
Бренд:

The effect of lasers of 3 wavelengths in the visible region - 476, 488 & 514 nm on mitotic & meiotic cell divisions, growth, yield & activity of specific enzymes were studied in two taxonomically diverse plant species - Allium cepa L. & Vicia faba. The effect of laser exposures was compared with the effect of two physical mutagens (gamma & UV radiations) and two chemical mutagens (Ethyl Methane Sulphonate and Hydroxyl amine; EMS & HA). The study indicated that lasers could be mutagenic causing aberrations in the mitotic & meiotic cell divisions & producing changes in the growth & yield of the plants. Lasers of higher wavelengths 488 & 514 nm caused aberrations in the early stages of mitotic cell division whereas lasers of lower wavelengths (476 nm) caused more aberrations in later stages. Laser exposure of 488 nm wavelength at power density 400 mW induced higher mitotic & meiotic aberrations & also induced higher pollen sterility than lasers of 476 & 514 nm. The frequency of mitotic aberrations induced by lasers was less than that caused by gamma-irradiation but comparable to that induced by EMS & HA. Lasers also stimulated growth & yield. Lasers cause more mutation than UV.

ELISA - Enzyme Linked Immunosorbent Assay

ELISA - Enzyme Linked Immunosorbent Assay venkatachalam deepa parvathi and maddaly ravi anti mitotic polyclonal antibodies for mitotic inhibition
Бренд:

In ELISA formats there are several parameters that are common and critical to assay performance and should be considered during the optimization process, including antibodies concentration, antigen concentration, incubation time of blocking, substrate solution and washing solution. Though immunoassays offer a specific, sensitive and rapid method to detect and quantify even trace amounts of allergens in foodstuffs, certain processes can denature, alter or destroy proteins so that they are no longer detectible by assay using antibodies. When using monoclonal antibodies, there is a great chance of obtaining false negatives in the detection. Polyclonal antibodies are recommended for ELISA techniques as the risk of obtaining false negatives is reduced as compared to monoclonal antibodies which are quite specific.

Detection of anti-ADAMTS13 antibodies in patients with TTP

Detection of anti-ADAMTS13 antibodies in patients with TTP venkatachalam deepa parvathi and maddaly ravi anti mitotic polyclonal antibodies for mitotic inhibition
Бренд:

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disease caused by a deficiency in ADAMTS13 which in the acquired form is provoked by autoantibodies against this protease. The main objective of this work was to study the pathophysiologic and prognostic value of anti-ADAMTS13 antibodies in patients with acquired TTP. The surveyed antibody profile revealed the presence of mainly IgG followed by IgA and IgM antibodies. IgG1-4 and IgA ADAMTS13-specific immune complex (ICs) were detected. IgG4 was the most prevalent IgG subclass, present either as free antibody or as ICs. IgG antibodies in combination with high inhibitor titers at disease presentation were associated with persistence of undetectable ADAMTS13 activity in clinical remission. TTP patients with high IgG4 and undetectable IgG1 levels were more prone to relapse than patients with low IgG4 and detectable IgG1 levels suggesting that IgG4 could be a useful biomarker for identification of patients at risk of disease recurrence. The comprehensive characterization of anti-ADAMTS13 antibodies as well as circulating ADAMTS13-specific ICs may contribute to a better understanding of the mechanisms leading to acquired TTP

Chromosome Segregation Defects of Adult Teleost Fish Brain

Chromosome Segregation Defects of Adult Teleost Fish Brain venkatachalam deepa parvathi and maddaly ravi anti mitotic polyclonal antibodies for mitotic inhibition
Бренд:

In contrast to most other vertebrates,teleost fish exhibit an unparalleled capacity to generate stem cells in both the intact and the injured adult brain.My research is focused on the occurrence, the extent and the fate of aneuploid cells (genome-modified individual cells characterized by the loss or gain of whole chromosomes) generated in the teleostean brain. Aneuploidy arises through various chromosome segregation defects during the mitotic divisions of newly-generated cells in the adult brain. Aneuploidy is observed in ~80% of the newly-generated stem cells of the adult brain,but occurs at a very low rate in liver tissue, as shown by metaphase chromosome spreads and flow-cytometric DNA content analysis. The mitotic machinery of adult brain cells was examined for chromosome segregation defects which showed lagging chromosomes at metaphase and anaphase, as well as micronuclei and anaphase bridges,in the intact adult brain. In conclusion,my research demonstrates the evidence of the generation and maintenance of aneuploid cells in the adult fish brain that arise through chromosome missegregation which is a widespread phenomenon in the teleostean central nervous system.

Anti-variant surface antigens pregnancy-associated malaria antibodies

Anti-variant surface antigens pregnancy-associated malaria antibodies venkatachalam deepa parvathi and maddaly ravi anti mitotic polyclonal antibodies for mitotic inhibition
Бренд:

In malaria endemic regions, pregnant women and their newborns are at high risk of developing severe symptoms of malaria caused by Plasmodium falciparum. Placenta-sequestering malaria parasites involved in the pathogenesis express particular Variant Surface Antigens (VSAPAM) on the surface of infected erythrocytes (IEs). The mechanism underlying the association between PAM, placental pathology and poor pregnancy outcome remained poorly understood in human. Thus, the development of animal models to help understand these mechanisms is of utmost importance. The present study showed that pregnancy status and intensity of Plasmodium falciparum transmission can affect acquisition of Immunoglobulin G Subclass responses to VSAPAM in Cameroonian women. Observations from mice model suggest that levels of antibodies specific for recrudescence-type IEs are related to the protection of pregnant mice and their offsprings from poor outcomes. Alterations of cytokine levels may also strongly contribute to poor pregnancy outcome. The study of Plasmodium berghei malaria in pregnant, immune mice can be used to gain a better understanding on the mechanisms of malaria pathogenesis and immunity.
