Gastroenterologia Japonica, 1979
A sensitive and specific radioimmunoassay for rat and human serum ligandin was developed using antisera generated in rabbits by the injection of ligandin purified from liver. Because rat ligandin and human ligandin have no cross reactivity, radioimmunoassay systems for each of the serum ligandins were prepared. Highly purified ligandin labeled with125I

Radioimmunoassay is often described in terms of the competition between a radiolabeled antigen (Ag*) and its unlabeled counterpart (Ag) for binding to a limited amount of specific antibody (Ab) (1). In most radioimmunoassays the reaction is allowed to proceed to equilibrium and thus, can be represented by Eq. (1). [Formula: see text].

Radioimmunoassay for immunoconglutinins
Journal of Immunological Methods, 1980A competitive radioimmunoassay for immunoconglutinin (IK) was developed using isolated antostimulated rabbit IK labelled with 125I and glutaraldehyde-fixed sheep erythrocytes coated with fixed complement (EAC). IKs in test sera of human or animal origin produced specific inhibition of uptake of [125I]IK onto EAC and this was quantitated by reference to

We describe a radioimmunoassay for digitonin which utilizes the ability of digotonin to compete with 125I-labeled digoxigenin for binding to anti-digoxin antiserum. As performed using the Gammaflo automated radioimmunoassay system and commercially available reagents, the assay can detect as little as 20 micrograms/ml (15 microM) digitonin. The assay is

Radioimmunoassay of Angiotensin
Nature, 1968HABER et al.1 showed that antibodies elicited in rabbits by copolymers of angiotensin with poly-L-lysine can be used for radioimmunoassay of angiotensin. The following are details and some results of the method we have developed. Comparing the binding affinity of three different rabbit antisera to Val5-angiotensin II amide (‘Hypertensin’, Ciba) and ...

Seminars in Nuclear Medicine, 1975
The powerful nuclear medicine tool of radioimmunoassay was very rapidly developed because of the favorable properties of insulin in such a procedure. The current method of insulin immunoassay in our laboratory is described, with emphasis on the details of the separation of bound and free using talc tablets; emphasis is also given to the correction for ...

Biochimica et Biophysica Acta (BBA) - Protein Structure, 1977
Abstract A sensitive and specific radioimmunoassay has been developed for rat ligandin, capable of measuring this protein in the manogram range. The assay employs [125I] ligandin prepared by the chloramine-T method and rabbit antiserum to rat ligandin, with a double antibody method of separating antibody-bound from free ligandin.

Radioimmunoassay of the A prostaglandins
Prostaglandins, 1972Antibodies to the A prostaglandins (PGA) were produced in rabbits immunized with a conjugate of prostaglandin E2 (PGE2) covalently linked to bovine serum albumin (BSA) by reaction with carbodiimide reagent. A radioimmunoassay was developed using dextran-coated charcoal to separate the free from antibody bound PGA1-3H.

Radioimmunoassay for rhodopsin
Experimental Eye Research, 1980Abstract A radioimmunoassay for rhodopsin was devised using [125I]rhodopsin and antibody to purified bovine rhodopsin in a double antibody procedure that can quantify the concentration of this visual pigment when present in picomolar amounts. The method demonstrated a high degree of sensitivity, reproducibility, and specificity, and is applicable to ...

Several sensitive radioimmunoassay systems for secretin have been developed and reported1–6. The development of these assay systems depended upon the generation of a specific secretin antiserum and the iodination of secretin (natural porcine secretin, synthetic secretin or a tyrosyl derivative of secretin).
