Generation of human scFv-IgG1Fc antibodies for detection of lymphatic filarial recombinant antigens, BmR1 and BmSXP.

Lymphatic filariasis is a neglected parasitic disease that affects millions in tropical and subtropical countries and is caused by Wuchereria and Brugia species. Specific and sensitive detection methods are essential in mapping infected areas where rapid tests are needed to cover underdeveloped and remote regions, which facilitates eliminating the disease as a public health problem. A few commercialized rapid tests based on antigen or antibody detection are available, but the former only detects infection by Wuchereria species and cross-reacts with nonlymphatic filaria, whereas antibody detection might provide positive results of previous infection.

Identification and molecular docking study of novel cholesterol esterase inhibitory peptides from camel milk proteins.

Novel bioactive peptides from camel milk protein hydrolysates (CMPH) were identified and tested for inhibition of cholesterol esterase (CEase), and their possible binding mechanisms were elucidated by molecular docking. Papain-generated CMPH showed the highest degree of hydrolysis. All CMPH produced upon enzymatic degradation demonstrated a dramatic enhancement of CEase inhibition compared with intact camel milk proteins, with papain-generated hydrolysate P displaying the highest inhibition.

Identification of Pinto bean peptides with inhibitory effects on α-amylase and angiotensin converting enzyme (ACE) activities using an integrated bioinformatics-assisted approach.

Five Pinto bean peptides with α-amylase and angiotensin converting enzyme (ACE) inhibitory activities were successfully identified using the integrated bioinformatics approach. By using PEAKS studio, 511 peptide sequences were first shortlisted based on their de novo sequence property and average local confidence (ALC) yield of ≥60%. Subsequently, only five peptides were found to have high potential (score ≥0.

Screening and identification of five peptides from pinto bean with inhibitory activities against α-amylase using phage display technique.

The objective of this study was to screen and identify α-amylase inhibitor peptides from Pinto bean. Five Pinto bean bioactive peptides were successfully identified: PPHMLP (P1), PLPWGAGF (P3), PPHMGGP (P6), PLPLHMLP (P7) and LSSLEMGSLGALFVCM (P9). Based on ELISA results, their promising optical density values were 1.

Enzyme-assisted extraction and identification of antioxidative and α-amylase inhibitory peptides from Pinto beans (Phaseolus vulgaris cv. Pinto).

Antioxidant and α-amylase inhibitor peptides were successfully extracted from Pinto bean protein isolate (PBPI) using Protamex. A factorial design experiment was conducted and the effects of extraction time, pH and temperature were studied. pH 7.

A comparative study of physicochemical characteristics and functionalities of pinto bean protein isolate (PBPI) against the soybean protein isolate (SPI) after the extraction optimisation.

Optimisation of protein extraction yield from pinto bean was investigated using response surface methodology. The maximum protein yield of 54.8 mg/g was obtained with the optimal conditions of: temperature=25 °C, time=1 h and buffer-to-sample ratio=20 ml/g.
