Filed: 1968-09-03
Abstract: 1,248,764. Determination of reagin-Ig using labelled antibodies. PHARMACIA AB. 3 Sept., 1968 [6 Sept., 1967], No. 41801/68. Heading B1X. Labelled antibodies against reagin Ig or against fragments of reagin Ig are used to determine reagin Ig (reagins are antibodies against allergens). The antibodies may be labelled with a radioactive isotope, for example I<SP>125</SP>, or with a fluorescent group using for example fluorescein isothiocyanate. Means for determining reagins comprises a first reagent comprising a water-insoluble polymer having bound to it allergen against which the reagin to be determined is directed and a second reagent comprising the labelled antibodies as above. The sample is incubated with the first reagent when any reagin present in the sample becomes attached to the polymer particles; the polymer particles are separated from the liquid phase, washed and then incubated with the second reagent. The solid and liquid phases are separated again and the radiation in either phase determined and compared with that in a control. The water-insoluble polymer is preferably particulate but may be in the form of discs, strips or a test tube wall and may be a copolymer of a polyhydroxy compound for example dextran, starch, dextrins, polyvinylalcohol with a bifunctional substance. The allergen may be physically or chemically bound to the polymer. Examples relate to Sephadex (RTM) as carrier, birch pollen as allergen and I<SP>125</SP>-labelled rabbit antibody.

In the exchange shown the time channels on incoming highways EML1-N are connected with the time channels on outgoing highways SML1-N through pairs of intermediate lines with complementary delay stores Z0, Z6; Z3, Z3<SP>1</SP> and the actual connection is made by switches controlled by rotary address stores UI-UN operating through decoders DEI-N, DSI-N. A special pair of intermediate lines-SV1, SV2 is provided for the collective connection. Information emanating from the first subscriber is stored in the register ZZ which acts as a rotary word store by the action of gates SG and OG so that the stored information can be entered into each collective subscriber's time slot on the outgoing highways. The store is stopped and refilled from the incoming highway for each time frame by applying a signal S to gate SG. For the second subscribers the information appearing in their time slots on the incoming highway is passed through a code converter to change it into a 12 bit code and is serially stored in register R. The bits are passed in parallel into the adder where they are recirculated through the register RR so that as each word arrives from each of the second subscribers it is added to the word(s) already present to make up a total word. At the correct instant the total word is passed to code converter LN where its original 8 bit form is restored and it is transmitted to the first subscriber in the correct time slot on the outgoing highway.
