Titering Antibodies

Current Protocols in Cytometry, 1997
AbstractFlow cytometry using fluorochrome‐conjugated antibodies has emerged as a major approach to automated cellular identification. One of the most important issues in immunophenotyping is using the correct amount of antibody. This unit presents techniques for ascertaining the optimal titer for individual, dual, and multiple antibodies used for ...

The Use of TORCH Titers

Pediatrics, 1983
Of 603 patients undergoing serologic tests for Toxoplasma, syphilis, rubella, cytomegalovirus, and herpes simplex (TORCH tests) during a 4-year period, 381 (63%) were infants younger than 6 months and 110 (18%) were either the mothers of those infants or pregnant women.

A retrospective study of the added value of parallel titers compared with serial titers

Transfusion, 2019
BACKGROUNDPrenatal antibody titers for alloimmunized patients are subject to multiple sources of variation. A parallel titer on the previous sample at the same time as the current sample is recommended. The purpose of this study was to determine the added value of parallel titers.STUDY DESIGN AND METHODSThis is a retrospective study of samples from ...

Serum erythropoietin titers in the aged

Mechanisms of Ageing and Development, 1988
Erythropoietin (Epo) titers in the aged (from 70 to 89 years) were determined by a radioimmunoassay. Epo levels in normal elderly subjects were not different from levels in the young volunteers. The serum Epo levels in elderly patients with anemia were inversely related to hemoglobin levels; their regression coefficient was not worse than that found in

Regulation of the Juvenile Hormone Titer

Annual Review of Entomology, 1981
Juvenile hormone (JH) is produced by the corpora allata (CA) of insects. It regulates development and reproduction and also plays a crucial role in polymorphism. These functions have been amply reviewed (13, 21, 23, 29, 30, 112, 141). However, little information is available on the mechanisms of these effects, mainly because of the difficulty in ...

Protein a chromatography at high titers

Biotechnology and Bioengineering, 2013
ABSTRACTThe large increase in antibody titers over the past two decades has created significant challenges for downstream processes; however, there have been no quantitative studies of the effect of feed concentration on the dynamic binding capacity in Protein A chromatography.

High Titer Glucagon Antisera

Endocrinology, 1977
Antibody titers in rabbits immunized with glucagon conjugated to albumin using difluorodinitrobenzene rose rapidly. Under conditions of immunoassay, less than 2 nl of serum from two of four animals and approximately 4 nl from the other two was required to bind 50% of the 10 pg of [125I]iodoglucagon 100 days after immunization.
