The control of prophenoloxidase activation in larval haemolymph of Calliphora

Journal of Insect Physiology, 1970
Spontaneous activation of prophenoloxidase on exposure to air occurs most rapidly in haemolymph from early (day 4) and late (day 11) third instar larvae of Calliphora. On and after day 6 of development, haemolymph contains an inhibitor of proenzyme activation which can be removed by ultrafiltration.

Haemolymph proteins of the honey bee—I. Separation and characterization of haemolymph proteins of worker larvae

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1971
Abstract 1. 1. Characterization of haemolymph proteins of honey bee worker larvae by several electrophoretic methods and by ultracentrifugation revealed that they resemble by these criteria the human serum globulins, but not albumins. However, no immunological cross-reactions were found between the haemolymph and human, rabbit or avian sera. 2.

Activation of vertebrate complement by Helix pomatia haemolymph

Developmental & Comparative Immunology, 1984
Haemolymph plasma from the pulmonate snail Helix pomatia contains a constituent, not yet identified, which causes activation of vertebrate complement via the alternative complement pathway in fluid phase. The activation of vertebrate complement by snail plasma is closely analogous to the activation caused by cobra venom factor (CVF), the snake's C3b ...

Haemolymph lectin and the maturation of trypanosome infections in tsetse

Medical and Veterinary Entomology, 1990
ABSTRACT. The tsetse immune system has recently been shown to be involved in trypanosome maturation; lectin secreted in the midgut, normally responsible for preventing the establishment of midgut infections, induces established midgut trypanosomes to mature.

An investigation of haemolymph proteins in Lepidoptera

Journal of Insect Physiology, 1965
Abstract Ion exchange chromatography of the haemolymph proteins of Malacosoma americanum and Rothschildia orizaba on DEAE cellulose, yielded 5 and 4 fractions respectively. The esterase activity of each fraction was estimated. In both cases each fraction was characterized by the presence of certain specific proteins which were detected as ...

Investigation on the Haemocytes and Haemolymph of Honeybees

Journal of Apicultural Research, 1965
SUMMARYThe puncture of the dorsal or ventral sinus proved to be the best method of collecting haemolymph from workers and queens. Almost all the workers survived, but many older queens died after the operation.The number of haemocytes per cu. mm. of haemolymph decreased with increasing age of workers, from 20 914 at 1 day old to 11 174 at 30 days old ...

Haemolymph composition in spiders and scorpions

Comparative Biochemistry and Physiology Part A: Physiology, 1984
Abstract 1. 1. Published data on haemolymph were examined for patterns in its interspecific variation. 2. 2. Na and Cl dominate osmolarity in scorpions and some spiders, but in other spiders half the osmolarity is due to organic solutes. 3. 3.

Isolation and characterization of the haemolymph lipoproteins of Triatoma infestans

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1982
1. Three lipoproteins differing in hydrated densities were isolated by ultracentrifugal procedures from the haemolymph of adult and fasted Triatoma infestans. 2. They are the high density lipoprotein HDL (d = 1.115-1.152) and the two very high density lipoproteins VHDL-I (d = 1.190-1.231) and VHDL-II (d = 1.245-1.260).

Nitrogenous compounds in the haemolymph of the cricket, Acheta domesticus

Journal of Insect Physiology, 1969
Abstract The nitrogenous compounds present in the haemolymph of larvae and adults of Acheta domesticus have been determined and are reported with a discussion of the relationship of the results to previously published data.
