TLDR
Water soluble HL-A antigens isolated from a cultured human lymphocyte cell line derived from the peripheral blood of a normal donor inhibited cytotoxic reactions of monospecific anti-HL- A antisera in a pattern identical to that found upon direct and absorption typing of the donor's peripheral lymphocytes.
Abstract
Water soluble HL-A antigens isolated from a cultured human lymphocyte cell line derived from the peripheral blood of a normal donor inhibited cytotoxic reactions of monospecific anti-HL-A antisera in a pattern identical to that found upon direct and absorption typing of the donor's peripheral lymphocytes. The possibility of obtaining large quantities of cells from mass cultures now makes the chemical and biologic characterization of HL-A antigens a reality.

Salt extraction of soluble HL-A antigens.

TL;DR: Application of the hypertonic salt extraction method is now yielding sufficient HL-A antigen to begin the elucidation of the molecular basis of transplantation individuality.

Production of beta 2-microglobulin by normal and malignant human cell lines and peripheral lymphocytes.

TL;DR: Studies of the primary structure have shown a high degree of homology of p2-u with the constant domains of human IgG, and suggested that /?2-/( was a free immunoglobulin domain with effector function similar to that of the C H 3 domain of IgG (Peterson et al. 1972).

Evaluation of two sources of soluble HL-A antigens: platelets and serum.

TL;DR: While it is difficult to solubilize sufficient antigens from platelets for chemical characterization, it is possible to use these materials for biological applications such as pretreatment of kidney recipients, because of the low density of HL‐A determinants on platelets.

Cultured human lymphocytes.

TL;DR: Success in establishing human lymphoid cell lines from patients with various genetic, infectious, and malignant disorders and from normal persons has facilitated many new avenues of research.

Serological analysis of human deoxyribonucleic acid polymerases. Preparation and properties of antiserum to deoxyribonucleic acid polymerase I from human lymphoid cells.

TL;DR: The rat antiserum should be useful reagent for testing of novel DNA polymerases isolated in small quantities from human tumors for contamination with DNA polymerase I, which is present in abundance in proliferating tissue and often confuses the biochemical characterization of these novel enzymes.
