Hydrophobic interaction high performance liquid chromatography (HPLC) using TSKgel Phenyl-5PW was applicable to single-step purification of F(ab')2 fragments from pepsin digests of mouse monoclonal antibodies of IgG1 class. The digests were applied to the gel equilibrated with phosphate-buffered saline containing 1 M ammonium sulfate. F(ab')2 fragments were adsorbed onto the gel using the same ...

• Let X=R with orthonormal basis (e1, e2) and consider the set of concepts defined by the area inside a right triangle ABC with two sides parallel to the axes, with −−→ AB/AB = e1 and −→ AC/AC = e2, and AB/AC = α for some positive real α ∈ R+. Show, using similar methods to those used in the lecture slides for the axis-aligned rectangles, that this class can be (ǫ, δ)PAC-learned from training d...

In this paper, a study is made on two well-known operator matrices; the Rhaly Ra and generalized difference ?ab. Firstly, some compactness results for operators ?ab, whose purpose to help in describing their spectra, are derived. Next, general investigating spectra of such large class Banach sequence spaces established. These give complete description spectra. The obtained unify, extend improve...

The cytotoxic T-lymphocyte (CTL) response against the male-specific antigen H-Y in C57BL/6 (B6, H-2b) mice is regulated by the I-Ab and Db molecules. From previous studies, we concluded that the bm12 I-Ab mutant does not respond to H-Y, because of a deletion in its T-helper-cell repertoire. We now demonstrate that two Db mutants, bm13 and bm14, also fail to generate a CTL response to H-Y. The b...

A crucial role for CD1-responsive, MHC class II-unrestricted T cells in the generation of T cell IL-4 responses is suggested by the: 1) requirement for IL-4 to prime in vitro IL-4 responses by naive CD4+ T cells; 2) ability of TCR cross-linking to induce CD1-responsive T cells, but not conventional naive T cells, to produce IL-4; 3) failure of anti-IgD Ab to induce an IL-4-dependent IgE respons...

Using C-class functions, we demonstrate a few popular common coupled fixed point theorems on Ab-metric spaces and discuss some implications of the main findings. Additionally, provide examples to illustrate findings their applications both homotopy theory integral equations.
