A testosterone derivative of formula (I):
where n is an integer in a range of from 1 to 10, and Y represents an activated or ready-to-be-activated group allowing formation of an amide bond with a primary amine of a molecule. Conjugates including the testosterone derivatives and a marker, methods for determining the concentration of testosterone in a biological sample, and methods for preparing the testosterone derivatives are also provided.
Nucleotide derivatives useful in modified DNA probe synthesis are compounds having the formula (I) wherein either A is a radical of formula -NHCO-(CH₂) x-R³ and B is a substituted pyrimidine or purine residue, or A is a hydrogen atom and B is a radical of formula (II)
The terminal group R³ may comprise amino or carboxy groups, or a sugar moiety, or it may comprise a reporter group such as biotin, or luminol derivatives, or any other group which is detectable by Elisa or other means of detection. These compounds do not exist in natural DNA. The new compounds are useful as active monomers in a rapid and efficient procedure for the synthesis of DNA fragments and can be chemically incorporated in a DNA probe synthesis which allows total control over the extent and site of modification.
The invention features compounds, pharmaceutical compositions and methods useful for the treatment of neoplasia. In particular embodiments, the compounds of the invention are useful for the treatment of multidrug resistant neoplasia.

The present invention relates to a process for the qualitative and/or quantitative determination of an immunochemically reactive component, in which one or more labelled components are used, that are obtained by direct or indirect coupling of such a component or components to particles of an aqueous dispersion of a hydrophobic dye or pigment, or of polymer nuclei coated with such a dye or pigment.
During the reaction or after an adequate reaction time the nature and/or the quantity of the dye is determined in the test medium, or optionally after a separation of the bound and free labelled components in one of the fractions by methods known by themselves.

A method and composition for increasing ovulation in female cattle wherein the cattle are administered with the composition so as to produce a mean steroid binding antibody titre in the female cattle of from 1 in 100 to 1 in 5000 at the time of ovulation.
The composition comprises (i) a conjugate of a steroid androgen, such as androstenedione or testosterone, or of a steroid oestrogen, such as oestrone, and an immunogenic protein, such as human serum albumin, and (ii) acid anhydrides of the steroid derivative, the composition containing from 10 to 90% of the steroid moiety in the form of the anhydrides.
