Affinity chromatography of phospholipase A2 from Naja naja naja (Indian cobra) venom

Toxicon, 1985
A rapid and improved purification procedure is described for phospholipase A2 from the Indian cobra, Naja naja naja. The procedure is based on affinity chromatography of the venom through Affi-Gel Blue to obtain a 9-fold purification in one step. However, as there are multiple forms of the enzyme in the venom and other proteins do bind to Affi-Gel Blue,

Source of carbohydrate in a toxic protein from Indian cobra (Naja naja naja) venom

Toxicon, 1981
Abstract The principal neurotoxin of Indian cobra venom has been investigated to locate the source of carbohydrate present in it. The data indicate that the neurotoxin is not a glycoprotein, but contaminated with extraneous carbohydrate particles which might have originated from the cellulose or dextran medium employed in the purification procedures.

[Comparison of two Elapidae venoms: Naja naja and Naja nigricollis].

Annales pharmaceutiques francaises, 1991
In our study on the identification of snake venoms by electrofocusing technics, the protein profiles of Naja naja naja, Naja nigricollis pallida and Naja nigricollis West Africa were compared. The typical profile of venoms of Elapidae was easily identified in this comparison.

Indian Spectacled Cobra (Naja naja)

2021
The Indian cobra (Naja naja), which is popularly known as the Asian cobra, is also called the spectacled cobra because of its hood mark. It inhabits the Indian subcontinent but is also found in the northeastern parts of the country. The Indian cobra has received much respect and attention in Indian mythology.

Seasonal changes in the testis of the cobra, Naja naja (Linn)

General and Comparative Endocrinology, 1966
The tests of the cobra, Naja naja (Linn) undergo not only seasonal spermatogenetic changes, but also well-marked histochemical cycles involving both the interstitium and the seminiferous tubules. After the breeding season (April–May), the gonads regress and enter a spermatogenetically quiescent phase that lasts for 3 months.

Steroid synthesis by the seminiferous tubules of the snake Naja naja

General and Comparative Endocrinology, 1971
Abstract Seminiferous tubules of the cobra ( Naja naja ) testis have been incubated in vitro with labeled progesterone to determine whether they have any steroid-synthesizing capacity. Androstenedione and testosterone have been identified from the incubate by means of TLC and recrystallization techniques, thus indicating the capacity of this tissue

Immunization studies with Naja naja venom detoxified by photooxidation

Toxicon, 1968
Abstract Photooxidation of cobra venom by visible light in the presence of methylene blue resulted in a relatively slow detoxification of the venom. The γ-globulin isolated from rabbits immunized with the detoxified venom gave poor protection in the animal experiments. Possible reasons for the weak response of the immune serum are discussed.

Use of HPLC to demonstrate variation of venom toxin composition in the Thailand cobra venoms Naja naja kaouthia and Naja naja siamensis

Toxicon, 1992
The composition of the venoms of Naja naja kaouthia and Naja naja siamensis from different commercial sources has been investigated using both ion-exchange and reverse-phase high-pressure liquid chromatography (RP-HPLC) in order to investigate variation in toxin contents.

Peripheral versus central action of a toxin from indian cobra (Naja naja naja) venom

Toxicon, 1981
Abstract A homogeneous toxin (NT fraction) purified from Indian cobra venom produced (at 0·25–1·0 mg/kg) predominant respiratory paralysis prior to any effect on the contractions of tibialis anterior muscle (cats) and gastrocnemius muscle (rabbits). NT fraction produced no direct effects on cardiovascular system or nerve action potential.
