The Preparation of Partially Purified
The treatment of tuberculous meningitis is frequently hindered by the formation of exudate within the cerebrospinal spaces. This exudate may obstruct the cerebrospinal circulation and give rise to the complications of subtentorial, basal cistern, and spinal block. Furthermore, the presence of exudate predisposes to the occurrence of tuberculous arteritis, which is responsible for the cerebral a...

متن کاملPreparation of a purified antigenic cholera toxoid.
Purified cholera enterotoxin was prepared by methods described by Finkelstein and Lo Spalluto (1970). This toxin was detoxified by treatment with heat and formaldehyde. Heating cholera toxin at 60 C for 25 min resulted in the formation of a polymer named procholeragenoid by Finkelstein et al. (1971). The weak toxic activity of this product was removed by treatment with formalin. No residual tox...
متن کاملPreparation of purified GPCRs for structural studies.
Since the publication of the first X-ray structure of a GPCR (G-protein couple receptor) in 2000, the rate at which subsequent ones have appeared has steadily increased. This has required the development of new methodology to overcome the challenges presented by instability of isolated GPCRs, combined with a systematic optimization of existing approaches for protein expression, purification and...
